High-Power CW Fiber-Coupled Laser
LZFL808-5W-CW-105/125-PC
808 nm, 5 W, multi-mode fibre
The LZFL808-5W-CW-105/125-PC is a 5 W multi-mode continuous fiber-coupled laser at 808 nm. It delivers the output through a 105/125 um fiber with 0.22 NA and includes 30 dB back-reflection isolation for pump protection. The two-pin package is intended for integration into pumping, medical and industrial laser systems.
