Description
The Photodigm 830 nm DBR Laser Diode is a high-performance, edge-emitting semiconductor laser designed for precision optical applications. Built on advanced monolithic single-frequency Gallium Arsenide (GaAs) technology, this Distributed Bragg Reflector (DBR) laser provides a stable single spatial mode beam, ensuring minimal noise and high spectral purity.
With a nominal wavelength of 830 nm ± 0.6 nm, this laser diode operates within a power range of 80 mW to 180 mW and features a low threshold current of 50 mA for energy-efficient operation. It offers a narrow 500 kHz linewidth, excellent polarization stability, and high side-mode suppression ratio (SMSR), making it ideal for demanding optical applications.
Available in multiple packaging options, including Chip on Submount (CoS), TO-8, C-Mount, and Transmitter Optical Subassembly (TOSA), this laser diode provides flexibility for system integration. It is widely used as a low-noise pump source in biomedical diagnostics, imaging systems, and precision spectroscopy.
