Digital L-Type Module

The "L-Type" module is our fiber coupled, single-mode turnkey laser design. The electronics are integrated into a fully turn-key UL/CE and IEC-certified system with built-in safety features. The L-Type has a narrow spectral linewidth (< 0.1nmFWHM) with USB Connectivity with dual port USB hub. The side panel can be opened, and the “guts” of the laser (U-Type module) can be removed to allow for different wavelength compatibility.
