1792 ECCW
Narrow Linewidth CW External Cavity Laser Diode
Analog Lasers & Photodiodes
BROADBAND
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.
Features

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.
