Performance Highlights

The 1792 ECCW series external cavity laser is a cost effective

solution for a coherent laser source. The laser is fabricated in a

14-pin hermetically sealed butterfly package that incorporates

a bias tee circuit, an integrated thermoelectric cooler (TEC), a

thermistor, and a back facet monitor photodiode. The 1792

ECCW provides substantially lower phase noise and a longer

coherence length than other semiconductor lasers, including

DFB lasers. The wavelength stability is assured by design, eliminating the need

for wavelength lockers and complex feedback control circuits.

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-

lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess

of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended

periods can adversely affect device reliability.
