Description
The Photodigm IsoBragg™ 767.700 DBRH-IBragg is an advanced fiber-coupled optically isolated laser diode package designed for high-performance applications requiring single-frequency operation and exceptional optical isolation. Leveraging Photodigm’s proprietary Distributed Bragg Reflector (DBR) laser diode technology, this module delivers a single spatial mode output with superior power stability and efficiency.
The IsoBragg™ package features a monolithic Gallium Arsenide (GaAs) DBR laser diode that is edge-emitting and pre-aligned for optimal coupling into a 1-meter polarization-maintaining (PM) fiber with an FC/APC male connector. Integrated optical isolation (≥30 dB) ensures minimal back-reflections, protecting the laser from destabilization.
Designed with precision, the aluminum 6061 housing ensures thermal stability, while the integrated thermo-electric cooler (TEC) provides active temperature control. The power range of 10-50 mW and low-noise operation make it ideal for spectroscopy, atomic cooling, and quantum optics.
With its compact 58.0 x 40.0 x 29.0 mm footprint and high-reliability construction, the IsoBragg™ 767.700 DBRH-IBragg is an excellent solution for research and industrial applications requiring high spectral purity and long-term operational stability.
