Laser control, laser module exchange, and temperature stabilization is brought to the highest level with automatic current (power) control with photodiode monitoring and feedback via graphical user interface (GUI) on your PC. The "L-Type" modules 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 all safety features. The M-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 wavelengths to be “dropped-in”
