LZPM/LZFL Single-Mode PM Fiber Laser
LZPM-638-80m-4
638 nm, 75 mW typ, polarization-maintaining single-mode fiber
The LZPM-638-80m-4 is a 75 mW typ single-mode polarization-maintaining fiber-coupled laser module at 638 nm. It uses the same coaxial single-mode module structure and follows the corresponding single-mode parameters, with a PM fiber output and an extinction ratio of at least 20 dB. The output is delivered through a 4 um single-mode polarization-maintaining fiber, NA 0.13 and terminated with FC, SMA905, FC/APC.
