770.108 Single-Frequency DBR Fiber-Coupled|Optically Packaged IsoBragg
Description
The Photodigm IsoBragg™ 770.108 DBRH-IBragg is an advanced fiber-coupled laser diode module that integrates optical isolation (≥30 dB) for superior performance and stability. Designed with Photodigm’s proprietary Distributed Bragg Reflector (DBR) technology, this laser diode delivers single-frequency operation, high spectral purity, and excellent power output ranging from 10 mW to 70 mW.
Housed in a compact and robust aluminum 6061 package (58.0 x 40.0 x 29.0 mm), the IsoBragg™ couples its edge-emitting DBR laser diode into a 1-meter-long polarization-maintaining (PM) fiber with an FC/APC male output connector. This configuration ensures a highly stable single spatial mode beam, making it ideal for quantum optics, spectroscopy, and precision metrology applications.
With an integrated thermo-electric cooler (TEC) and thermistor, the module provides temperature stability and wavelength consistency, ensuring long-term operational reliability.
