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

Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress rat‐
ings only and operation of the device at these or conditions beyond these is not implied. Exposure to absolute maximum ratings forextended periods of time may affect device reliability.
