The device comprises a main unit, light guide arm and footswitch.The working principle of Q Switched Nd: YAG Laser machine is that neodymium ions in neodymium doped yttrium aluminum garnet crystals are excited by the energy provided by the pump source and release photons. These photons are repeatedly reflected and stimulated to emit in the optical resonant cavity of the crystal, ultimately producing a specific wavelength (mainly 1064nm) and high energy density laser beam. It can also be converted from a 1064nm wavelength laser beam to a 532nm laser beam through frequency doubling technology; Then, it is effectively transmitted to the treatment site through the beam transmission device and plays a therapeutic role through the photothermal effect.
A mains electricity (AC-powered) device assembly in which input energy (e.g., flashlamp, diode laser) is used to excite a glass/crystal rod to emit a high-power laser beam intended to cut, excise, ablate, and vaporize soft tissues in dermatological applications such as vascular/skin lesion, tattoo, and hair removal; it includes frequency doubling technology whereby the operator can select one of two energy wavelengths (1064 or 532 nm); it may include additional glass/crystal rods and pumping options to achieve additional laser wavelengths. It includes a light source, delivery/positioning device(s), and controls/foot-switch, and may be operated in continuous-wave or pulsed modes.
