Recent years, lasers have become foreign industrial machinery and processing industry in the important equipment, widely used in cutting, drilling, Korea hunger and heat treatment processes. Laser processing is not only easy to automate, and high economic efficiency.
Use lasers usually be processed according to the nature of the material, because different materials absorb different wavelengths suitable for the laser beam. Such as metal materials generally easy to absorb the laser beam wavelength of 1.06 m, while the plastic and ceramic composite materials are easier to absorb the laser beam wavelength of 10.6 m. Currently there are two commonly used laser, a carbon dioxide laser, the other is solid-state Nd – YAG laser.
Carbon dioxide laser is the most widely used lasers, the output power is 50 ~ 1500W, laser beam wavelength of 10.6 m, mainly used for cutting, drilling and welding. Use Laser Cutting At about the speed of 7.5m per minute under the cutting width of only 0.1 ~ 0.3mm, so, you can cut the “heat affected zone” to minimize, and were cut out of a clear outline, no burr. As the speed of laser drilling, and thus solve the cracking of the ceramic in the drilling of the problem, such as 0.6mm thick 1.3mm diameter ceramic drill blank each time only 0.3S. Some countries have been replaced with carbon dioxide laser beam welding, laser welding can be used as the electron beam did not have to be in a vacuum, which simplifies the process and reduce costs.
Solid state Nd – YAG laser into industrial applications, the time is relatively short, the output power is 10 ~ 400W, laser beam wavelength of 1.06 m, easily absorbed by metal material, currently used for low-power precision drilling and electronic industries in the sealing process and spot welding.
Japan’s Nissan Motor Co. steel surface by laser treatment to improve the gloss paint has been successful. This method is carried out in spray paint on the steel sheet prior to the surface with a laser beam etching process, is the steel plate surface diameter and depth of numerous tiny air evenly, and then to spray-paint treatment. This will not only improve the gloss, and paint is not easy to fall off. Volkswagen combination of laser and robot systems, processing and automotive dashboard shell, use the carbon dioxide laser power of 400W, the annual savings of processing costs 600,000 U.S. dollars. German car company, another carbon dioxide laser welding galvanized steel, mechanical visual system to monitor the welding process, greatly improve the efficiency of production. U.S. General Motors vehicles with power 1000W laser cutting of carbon dioxide into the exhaust pipe, not only improve the efficacy of 30%, and the cutting quality. Ford Motor Company uses 1500W of carbon dioxide laser cutting of PVC composite material, high efficiency, but also automation. Italian Fiat production line installed in the laser – the robot combined system, not only saves labor, but also to speed up the production process.
Russia will also be used for laser machining industry. A factory with the laser used on locomotive traction engine block for quenching success. Laser can be processed within one second surface heated to 1000, rapid quenching, completely avoid the deformation of the machining area, and to parts of the surface wear resistance increased by 50%.
The laser processing of a number of advantages, some countries also to develop new Laser processing machine Such as Japan and the United States created a laser machine. With the development of science and technology, laser applications in industry will be more extensive.
The art of laser dentistry is a more recent addition to the various techniques and methods that a dental professional can introduce to his patient. Despite being fairly new to the field, this form of treatment is highly praised by many doctors and is often recommended by dentists for many different dental applications. This technique is often used for either hard tissue treatment or soft tissue issues. Hard tissue means the tooth itself. There are many different uses for this technology and there are also a variety of ways that this is implemented.
Benefits with Hard Tissue
In this aspect, laser dentistry is used for preparing a tooth for the application of fillings as well as the detection of cavities. In this respect, it is faster than manual searching for cavities and also more thorough. It can detect the earlier signs of a cavity better than a dentist manually probing the nooks and crannies of a tooth. This is also a good way to minimize the patient

Like most treatments, laser therapy can benefit from image guidance. A Houston-based company has developed an MRI-guided system that has been tested and is now FDA-approved.
Laser induced thermal therapy (LITT) destroys unhealthy tissue, like cancer, with the intense heat supplied from a laser. The laser light is channeled through an optical fiber that can be inserted practically anywhere in the body. One of the biggest challenges in LITT is that the target cannot get too hot, otherwise it will char – thus preventing further laser light from penetrating into the tissue.
To avoid this, physicians have traditionally measured the temperature at some point near the target using a thermometer-like probe. But real-time imaging could provide a non-invasive means to monitor the temperature throughout the target region. In particular, MRI provides a sensitive temperature probe. The frequency of the MRI signal, which depends on the magnetic properties of water molecules, shifts as the temperature of the corresponding tissue changes.
Using this effect, Visualase, Inc., has developed a closed-loop MRI guided LITT system that provides the user with a temperature map of the target region and calculates the corresponding dose (i.e. the likelihood that cells in some region will die from the applied heat). If nearby healthy tissue is receiving too much heat, or if the temperature is approaching the charring temperature, the user can respond by changing the laser power or shutting it off, which helps to increase both the safety and efficacy of the procedure.
Trials of the system were independently performed on canines by R. Jason Stafford from the University of Texas M.D. Anderson Cancer Center, and his collaborators. Several LITT lesions were made in the brain, spine and prostate with MRI guidance. The results showed that the machine’s calculated dose matched up well with a post-operation assessment. Initial safety studies have also been performed in human patients and the device has recently received FDA approval. Stafford thinks MRI-guided LITT will provide a less invasive alternative to conventional surgery. He is currently working to improve the real-time targeting and heat delivery.
The research was described in the talk, “Closed-Loop Guidance of Laser Induced Thermal Therapy Using MRI,” presented July 31, 2008 at the 50th meeting of the American Association of Physicists in Medicine.

Entrepreneur Craig Nabat is Dedicated to Freeing the World from Nicotine Addiction using Quit Smoking Laser Therapy
Los Angeles, CA (PRWEB) March 23, 2006
Craig Nabat and his sky-rocketing company Freedom Laser Therapy is gearing up to go nationwide.
The man has ambitious plans to free the world from nicotine addiction using quit-smoking laser therapy. Many of Freedom’s clients are quitting with only one session.
Craig Nabat, a former smoker had not smoked a cigarette for 7 years. Then, one stressed out business trip in Hong Kong, he bummed a cigarette off a bar patron to make conversation. Immediately, he was addicted again, and ended up chain smoking the remainder of the trip.
“I am very passionate about this,” states Nabat, who says that getting off cigarettes was the hardest thing he has ever done in his life. “It took me years to quit smoking. Then, in a moment of bad judgment — I was back to smoking a pack and a half a day. I ended up struggling with the smoking addiction for the next year and a half.”
Nabat tried to quit smoking using the patch and gum without success. Then, he learned about a low-level laser therapy treatment being performed in Canada that could assist a smoker in breaking their addiction with one 30-minute session.
The treatment had been used successfully for smoking cessation in Europe and Canada for the past 35 years. “I’m from Detroit and ended up driving to Canada for the laser therapy. I began really hating smoking and knew it was killing me. It was killing me physically and I was feeling bad, but still couldn’t quit. I had the laser therapy and didn’t suffer any physical withdrawals. It was great! Next I got my mom, also a heavy smoker to get treated. “If she could get off smoking, then, I knew anyone could.”
Nabat researched the industry and waited for this laser technology to become legalized in the United States for clinical research trials. His plan: is to rapidly set up quit smoking laser therapy clinics throughout the United States. With an extensive marketing background, he decided to launch his company–Freedom Laser Therapy in Los Angeles — the capitol of revolutionary health & beauty treatments.
Nabat launched his first clinic in Los Angeles, California. “Word spread and people desperate to quit were coming…some of the biggest names in Hollywood were walking through the doors of Freedom Laser Therapy.”
Celebrities have incredible power and influence. And, they have ability to directly and indirectly drive millions of smokers to give up smoking. Statistics quote that as many as 50% of smokers say they started smoking after watching a favorite actor smoke on TV or in a film. Imagine how many teenagers might stay away from cigarettes in the first place, if celebrities no longer portrayed that it was cool.
Nabat moved to Los Angeles driven to help celebrities get off smoking, hoping once they did…they would let other smokers — especially young people, know how easy it is to quit using the laser therapy procedure.
There are 4,700 toxins in every cigarette — 60 cause cancer. Nabat says, “Cigarettes are just a bad product.” Within 5 years, States across the nation will ban smoking inside office buildings and restaurants. Smokers really will not be able to smoke anywhere in public.
According to Nabat, the key to quitting smoking is first break the physical addiction — that takes approximately three days. The laser probes stimulate specific acupuncture points on hands, face, ears and wrists, intended to alleviate nicotine withdrawals. Then the smoker is instructed to detoxify their body with provided vitamins and anti-oxidants, which are taken for the next 10 days.
“Smokers need to see cigarettes for what they are,” states Nabat. “This product was ingeniously marketed to all of us. People smoke because of nicotine, not cigarettes. It’s the only product on the market known to kill mass amounts of people and is still sold. 70% of smokers want to quit, but can’t. They’re addicted.”
Freedom Laser Therapy has two locations: Los Angeles, California and Detroit, Michigan and is opening other treatment sites around the world. Freedom Laser Therapy specializes in nicotine addiction and will ultimately offer drug & alcohol treatments in clinics staffed by healthcare professionals.
The low-laser therapy operates on the principles of acupuncture to help alleviate nicotine withdrawal symptoms. During treatment the client watches a video educating the smoker on their behavioral addiction, vitamins and antioxidants are provided, plus a quit smoking support kit that prefaces they can never take another puff of nicotine again.
Freedom Laser Therapy’s franchise company is set to open soon, it has been 3 years in the making. Nabat says, “My Main Goal is to Let Smokers Who Want to Quit Know That There is Now an Easier Way to Quit Smoking.”
