HIGH POWER DFB LASERS
Single frequency lasers in 14-pin butterfly package
AA1401 SERIES INCLUDING AA1402, AA1406, AA1408, and AA1415
The Gooch & Housego high power distributed feedback laser (DFB) is an InGaAs/InP multi-quantum well (MQW) laser diode.
The module is ideal in applications where low relative intensity noise (RIN) and stable polarization-maintaining properties are needed.
The module contains a thermo-electric cooler, thermistor, and monitor detector and is designed and built using G&H’s high reliability platform for defense applications.
