LZPM/LZFL Single-Mode PM Fiber Laser
LZPM450-30m-3.5/125
450 nm, 30 mW typ, polarization-maintaining single-mode fiber
The LZPM450-30m-3.5/125 is a 30 mW typ single-mode polarization-maintaining fiber-coupled laser module at 450 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 15 dB. The output is delivered through a 3.5 um single-mode polarization-maintaining fiber, NA 0.13 and terminated with FC/PC, FC/APC.
