Q-switched ND: YAG Laser

Description of Q-Switched Nd: YAG Laser:
Q-Switched Laser can be used in Laser Tattoo Removal to increase the power (not the energy!) of a laser pulse. By degrading the Q, or Quality of the laser resonator, pump energy is stored until the population inversion is complete and the gain medium is saturated with energy.
Features of Q-Switched Nd: YAG Laser
1. No injury to skin and hair follicle; no risk of scarring.
2. Instantaneous blasting high laser technology, international standard of production, technical test strictly.
3. This laser treatment instrument manufactured in China by us adopts imported stone Q-switch cassette mechanism, the entire solid laser, without replacing Q-switch.
4. Painless treatment, little side-effect.
5. This Laser Tattoo Removal is easy to operate.
Functions of Q-Switched Nd: YAG Laser
When the Q is restored, laser action begins very rapidly and depletes the population inversion, producing a very short (nanosecond domain) but very powerful pulse of laser light. Power = Energy/time, so although the pulses are powerful, the average energy output of a Q-Switched laser is actually lower than a "free running" pulsed laser. Q-Switching with very high (kHz) repetition rates can be operated in Quasi CW mode to simulate the operation of a much higher power CW or pulsed laser.
Application scope of Q-Switched Nd: YAG Laser
1. 1064nm: Also being used as Laser Tattoo Removal, this Q-Switched Nd: YAG Laser can remove birth mark, coffee spot, freckle, senile plaque, pigment from outside injure, black, blue tattoo, eye line, eye brown and lip line etc.
2. 532nm: As laser treatment instrument, this Q-Switched Nd: YAG Laser can treat red and brown pigment, red spot and mole, capillarectasis and brandy nose.
Work principle of Q-Switched Nd: YAG Laser:
Modulating the quality of a resonator can be active or passive.
In active q-switching, the switch is typically an externally controlled electro-optical device, in which voltage is used to change the refractive index of certain crystals (Pockels cell), blocking or transmitting light in the resonant path.
In passive q-switching, the "switch" is typically a saturable absorber which attenuates light transmission below a given threshold. As light intensity increases, the absorber of this laser treatment instrument becomes saturated and passes light in the resonant path, enabling laser action. The absorber desaturates after the laser pulse, blocking transmission and allowing the process to repeat. The saturable absorber can be a crystal, dye, or semiconductor , and because the process is passive, very high repetition rates are possible and design is simplified compared to active q-switching, but with much less control and lower pulse energies.
