Description
The 1090 nm DBR Laser Diode is a high-performance, single-frequency laser designed for atomic spectroscopy, particularly for strontium-based (Sr) applications. Utilizing Photodigm’s advanced monolithic Gallium Arsenide (GaAs) technology, this Distributed Bragg Reflector (DBR) laser delivers a stable, single spatial mode beam with passivated facets for enhanced reliability.
With a nominal wavelength of 1090 ± 0.6 nm, this laser diode offers exceptional wavelength stability, making it ideal for high-precision scientific and industrial applications. Available in multiple free-space packages, including Chip on Submount (CoS), 9MM TO-8, C-Mount, and TOSA, the device supports additional add-ons such as Mode-Hop Free (MHF) and Virtual Point Source (VPS) lenses for tailored optical performance.
Operating at a maximum power of 180 mW, this DBR laser ensures low threshold current (50 mA) and high slope efficiency (0.8 W/A), delivering excellent performance across a wide temperature range (5°C to 70°C). Its compact form factor and fundamental mode structure make it a top choice for researchers and engineers seeking reliable, high-precision laser sources.
