Oriental-laser designed various structures of micro channel diode laser stack including OL (S), DLS, FLT, SYN, AL series. Compare to macro channel laser, micro channel laser has better heat dissipation, so with same peak power, micro channel average power and duty cycle can reach more than twice of macro channel laser. Also in pulse condition, laser hair removal affection and speed can be double as the same power of macro channel laser. Single bar peak power 50W,100W,200W can be optional,waves are also 760-1060nm optional.
