ARC packaging diode laser stack

ARC packaging diode laser stack

We make the QCW laser into an arc, which is benificial to the lightweight design of the pump structure. Au-Sn packaging technology makes the laser have high reliability even in harsh working environment.

QCW diode laser module in arc heatsink
