2m窄线宽激光器EP2000-DM-B Series
EP2000-DM-B是一个性价比高 窄线宽，高度相干的激光光?类似于DFB形式?*技术， 即：ridge waveguide technology and epistructure design is used to deliver an InP-based strained quantum-well laser diode source emitting at a wavelength of 2.0m with high SMSR. The Discrete Mode laser diode chip is packaged in an industry standard hermetically sealed 14 pin butterfly package with integrated optical isolator thermo-electric cooler (TEC) monitor photodiode and thermistor.
