Description
The 808 nm Series Distributed Bragg Reflector (DBR) Laser Diode is engineered for precision and reliability in high-performance applications. Utilizing Photodigm’s advanced monolithic single-frequency Gallium Arsenide (GaAs) laser technology, this edge-emitting laser diode delivers exceptional performance with a single spatial mode beam. Designed for biomedical diagnostics, imaging, and other critical applications, the 808 nm DBR diode features passivated facets for enhanced durability and longevity.
This laser operates with a nominal wavelength of 808 nm (±0.6 nm) and provides a power range of 80-180 mW, achieving a maximum optical power of 180 mW at 250 mA. The laser’s low noise, high slope efficiency of 0.85 W/A, and optimized threshold current of 60 mA make it ideal for low-noise pumping sources. The 808 nm Series also offers a wide operating temperature range of 5°C to 70°C and is available in various package options, including Chip on Submount (CoS), Mode-Hop Free (MHF), and Transmitter Optical Subassembly (TOSA) configurations.
