767 Single-Frequency DBR Fiber-Coupled|Optically Packaged IsoBragg
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.

Frequently Asked Questions
The IsoBragg™ package integrates fiber coupling and optical isolation (≥30 dB), minimizing back-reflections that can destabilize the laser. This ensures higher stability, spectral purity, and ease of integration compared to standard DBR laser diodes.
The laser is coupled into a 1-meter-long polarization-maintaining (PM) fiber with an FC/APC male connector, ensuring minimal insertion loss and maintaining a single spatial mode.
This laser is ideal for atomic and molecular spectroscopy, laser cooling and trapping, quantum optics, high-resolution metrology, and biomedical imaging, where high spectral purity and optical isolation are essential.
The IsoBragg™ module is ESD-sensitive, requiring a grounded work area, wrist strap, and proper storage in an antistatic container to prevent damage.
The integrated thermo-electric cooler (TEC) provides precise temperature control with a TEC current range of ±1.9 A and a TEC voltage range of ±2.8 V, ensuring long-term laser wavelength and power stability.
