High-Power CW Fiber-Coupled Laser

LZFL940-10W-105/125-SMA905

940 nm, 10 W, multi-mode fibre

The LZFL940-10W-105/125-SMA905 is a 10 W multi-mode continuous fiber-coupled laser at 940 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.
