Description
The 1083.33 nm DBR Laser Diode is a high-performance, single-frequency laser based on advanced Gallium Arsenide (GaAs) monolithic technology. Designed for atomic spectroscopy applications, it provides a stable single-spatial-mode beam with passivated facets for enhanced reliability. This laser is particularly suited for metastable Helium (He*) spectroscopy and other high-precision optical applications, offering a guaranteed wavelength accuracy within ±10°C from room temperature.
Available in low-power (40–120 mW) and high-power (100–350 mW) configurations, the diode features a high side-mode suppression ratio (SMSR) of over 40 dB, ensuring minimal spectral noise. Its precise wavelength tuning capabilities, facilitated by temperature and current adjustments, make it an ideal solution for scientific research and industrial applications requiring stringent frequency stability.
For integration flexibility, the 1083.33 nm DBR Laser Diode is available in multiple package options, including Chip on Submount (CoS), TO-8, C-Mount, and Transmitter Optical Subassembly (TOSA). Additional optical enhancements, such as Mode-Hop Free (MHF) and Virtual Point Source (VPS) lenses, further optimize its performance.
