General Description
The EM4 high power distributed feedback laser (DFB) is a CW InGaAsP/InP multi-quantum well (MQW) laser diode. The module is ideal in applications where high power, low RIN and stable PM properties are needed. The module contains a cooler, thermistor and monitor detector. The module is designed and built using EM4s high reliability platform for defense components.
