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
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.
