ECCW Narrow Linewidth CW External Cavity
Laser Diode
The 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 ECCW provides substantially lower phase

Absolute Maximum Ratings
1
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute 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.

Absolute maximum data are limited to system design only; proper device performance is not guaranteed over rating listed above. Operation
beyond these maximum conditions may degrade device performance, lead to device failure, shorter lifetime, and will invalidate the device
warranty.
o
TEC current should not exceed 2.0 A during turn on, and case temperature under any conditions should not change faster than 10 C/min.
Soldering iron only; no reflow or dip soldering allowed.
See mounting recommendations below.
