Frankfurt Laser Company presents 689nm Discrete Mode Laser Diode
The 689nm discrete mode laser diode from the FEBP series is a cost effective, highly coherent laser source with a typical linewidth of 4MHz. A strained multi-quantum well discrete mode (DM) laser diode chip is packaged in an industry standard hermetically sealed TO39 can with integrated thermo-electric cooler (TEC) and thermistor. The typical optical output…
