The EP689-DM-BC laser diode module is a cost effective, highly coherent laser source that operates at a wavelength of 689nm with high SMSR. This laser diode has been developed using the patented discrete mode (DFB-like) ridge waveguide technology with an epistructure design to deliver an InP-based strained quantum-well laser diode source. The Discrete Mode laser diode chip is packaged in an industry standard, hermetically sealed 14 pin butterfly package with thermo-electric cooler (TEC) and thermistor.
