VCALASER VCSEL Laser Stack
VCSEL Theory
The vertical cavity surface emitting laser, or VCSEL , is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers (also in-plane lasers) which emit from surfaces formed by cleaving the individual chip out of a wafer. The System use high-power super-emitting chips as a light source, crystal guide pyramid shaping and transmission of NIR beam, act on subcutaneous, melanin in hair follicle absorb heat
Main Features:
Non Channel
810nm Pulse wavelength
Low threshold currents enable high-density arraysBeam quality: Narrow spectral width &Uniform emission & illumination
Life Span: 100 million can reach,3-5 times longer lifetime than channel diode laser
Lower temperature-sensitivity compared to edge-emitting laser diodes
