776.061 Single-Frequency DBR Fiber-Coupled|Optically Packaged IsoBragg
Description
The Photodigm IsoBragg™ is a state-of-the-art fiber-coupled and optically isolated laser diode package, delivering high-power performance in a compact and efficient design. Utilizing Photodigm’s proprietary Distributed Bragg Reflector (DBR) laser diode, this package ensures a single spatial mode beam with exceptional spectral purity and stability.
Engineered for precision, the IsoBragg™ incorporates polarization-maintaining (PM) fiber coupling with an FC/APC male output connector for seamless integration into high-performance optical systems. With a typical optical isolation of ≥ 30 dB, it offers superior protection against back reflections, ensuring long-term operational reliability.
The rugged aluminum 6061 package houses advanced thermal management features, including a thermo-electric cooler (TEC) with bidirectional current and voltage control. A narrow linewidth of 500 kHz ensures superior coherence for demanding applications.
With a wavelength of 776 nm and an output power range of 10–70 mW, the IsoBragg™ is ideal for quantum optics, precision spectroscopy, and other high-precision photonics applications.
