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 con-
tains a cooler, thermistor and monitor detector. The 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 ratings only and operation of the
device at these or conditions beyond these are not implied. Exposure to absolute maximum ratings for extended periods of time may affect device reliability.
