The results of computer simulations depicting various laser wavelengths aimed at virtual bacterial colonies buried in gum tissue suggest that use of lasers in oral debridement is effective in killing disease-causing bacteria and promoting dental health. The module features a new generation of multimode laser diodes with E2 front mirror passivation that prevents Catastrophic Optical Damage (COD) to the laser diode facet. Quantum cascade laser diode: This is a form of heterojunction laser diode which the difference between well energy levels is used to provide the laser light generation. The agent accumulates in tissue such as cancer cells and absorbs laser radiation at the specific wavelength. World Star Tech offers 405nm, 650nm and 785nm laser diodes in 5. Wainner, Michael B. Diode Laser Wavelengths. Laser light in the visible and near infrared spectrum 400 - 1400 nm (the majority of lasers used in dermatology) contributes to the so-called "retinal hazard region" and can cause damage to the retina, while wavelengths outside this region (i. This portion is added to my previous response: There are various reasons for the wavelength to get shorter rather than longer when the injection current is increased. This section responds to the Control System section by driving current to the laser diode. Picosecond Diode Lasers, Pico-LDs, are designed and manufactured by CrystaLaser. For example if you are targeting pigment in the hair follicle a deeper wavelength (640nm-1064nm) would be used, however most lasers used for hair removal are Diodes (800nm-900nm).
