  • 785nm Single-Frequency (SLM) Semiconductor Single-Longitudinal-Mode Laser

    Single‑frequency (SLM) 785 nm lasers are very popular in Raman spectroscopy. At this wavelength, good fluorescence suppression is observed, as many fluorophores are not readily excited in the near‑infrared range. The small footprint and +5 VDC (typically USB) operating voltage are exactly what handheld and portable devices require. Integrated precision drive electronics ensure low noise and very stable operation over a wide temperature range. The 785 nm near‑infrared laser features low photon energy. At the same time, our technology provides a low‑cost solution for demanding Raman spectroscopy needs.

    Product features:Compact size, 50 × 30 × 18 mm, suitable for integration;Identical dimensions and same control interface for easy interchangeability; 5 V supply, low power consumption, suitable for battery‑powered systems;Multiple wavelengths available ; Digital and analogue modulation; Optional fibre‑coupled output (SM, PM, MM); Space‑saving pin‑header connector for easy OEM integration control;Automatic power control (APC);TEC cooling; User‑friendly software interface l Part Number

    Part Number:MP-SLM-785-100-FS

    Application area:Raman spectroscopy research | Seed source
