Description
The Photodigm IsoBragg™ is an advanced fiber-coupled laser diode package designed for high-performance applications requiring optical isolation. It integrates Photodigm’s proprietary Distributed Bragg Reflector (DBR) laser diode technology, ensuring a single spatial mode beam with exceptional stability and precision. The monolithic single-frequency GaAs design enables superior coherence and narrow linewidth operation.
The IsoBragg™ package offers enhanced reliability with a robust Aluminum 6061 enclosure and features a polarization-maintaining (PM) fiber for stable beam transmission. The FC/APC male connector ensures low-back-reflection coupling, making it ideal for applications requiring high optical isolation (≥ 30 dB).
Designed for precision optical setups, the IsoBragg™ provides power outputs ranging from 10 mW to 110 mW and supports TEC-controlled thermal stability for consistent performance across varying conditions. With its compact 58.0 x 40.0 x 29.0 mm footprint, the IsoBragg™ is a powerful solution for spectroscopy, quantum optics, and advanced metrology applications.
