A laser diode firing circuit for a light detection and ranging device is disclosed. The firing circuit includes a laser diode coupled in series to a transistor, such that current through the laser diode is controlled by the transistor. The laser diode is configured to emit a pulse of light ...
The GreenLight laser emits laser radiation at a wavelength of 532nm. The tissue target chromophore is the hemoglobin molecule, which has a very high absorption coefficient at this wavelength. Laser radiation into the tissue is delivered using a side-firing fiber. In general, this laser is used ...
Built-in haptic technology can be enabled on the foot pedal to provide the operator with a tactile indicator that the laser is firing. Haptic touch is also available on the handpiece during preset photobiomodulation procedures to add physical sensation for the patient during treatment. The Gemini...

A laser diode converts electricity into light that's emitted in a tight beam. The conversion happens when an electrical current is applied to the diode, causing the electrons and holes in a P-N junction to recombine and release energy. This energy is in the form of photons of coherent lig...
the keloids scar, therefore cannot create hyperpigmentation. In particular keloids had a significant reduction of pigmentation at 21.3%. This indicates that melanin is not absorbed by the 1470 nm wavelength. Moreover, the fibre laser may destroy melanin deposits, reducing the pigmentation of the ...
LASER stands for Light Amplification by Stimulated Emission of Radiation. A P-N junction is formed by two layers of doped Gallium Arsenide where a High reflective coating is applied to one end of the junction and a partial reflective coating at the other end. When the diode is forward biased...
The term firing refers to the initiation of a latched state. To get a Shockley diode to latch, the applied voltage must be increased until breakover is attained. Though this action is best described as transistor breakdown, the term breakover is used instead because the result is a pair of ...
The use of lasers and flashlamps in these devices has not only proven to be safe and effective, but unlike electrolysis allows for the treatment of multiple hairs at a time, greatly improving coverage rate. Light-based epilation with lasers is often termed “laser hair removal”, although ...
