Product Overview:

1546.9nm Fitel FOL15DDBA-A31-19380-E 10mW DFB Laser

DFB's offer several key differentiating features relative to other types of semiconductor lasers. These features include their single frequency emission profile, their high stability and their ability to be tuned to adjacent wavelengths. These single frequency lasers employ Bragg diffraction gratings (mirrors) in their active gain region to form a waveguide. Unlike Fabry-Perot lasers, which utilize mirrors at both ends of the laser cavity, the reflection of the laser light in a DFB laser is along the entire cavity. This design principle allows them to deliver their single mode beam profile. DFB semiconductor materials include indium-phosphide and gallium-indium-arsenide-antimony.

Proper Handling and Operation of Laser Diodes:

DFB's, like all semiconductor lasers, are highly susceptible to damage from ESD and from temperatures exceeding their specified safe operating range. The user is advised to use care and proper ESD safety practices when handling them to avoid damage to the laser. A properly rated low noise current source, a low thermal resistance mount and a temperature controller should be used for optimal device performance and reliability.
