Description

The Thorlabs Fiber Coupled Laser Sources are fiber optic laser sources that provide ease of coupling
and simple control of laser diode driven fiber optics. These laser sources are available in two versions, Fabry-
Perot and Distributed Feed Back (DFB). The Fabry-Perot version comes in five available wavelength choices
from 635nm up to 1550nm. The DFB version comes equipped with a thermo-electric cooler to stabilize the output
wavelength, and a 40dB optical isolator to eliminate frequency jitter due to back-reflections. The DFB is available
in 1310nm and 1550nm wavelengths.
