Description
This model of single-frequency (SLM) 405 nm lasers is widely used in compact Raman spectrometers. Small footprint and +5VDC (USB typical) operating voltage is exactly what's needed for handheld portable devices. Integrated precision driver electronics ensure low-noise and very stable operation throughout the wide temperature range. 405 violet radiation features high energy photons, therefore much lower power is enough for efficient excitation of fluorescence or Raman scattering.
This free-space laser can be supplied with an integrated optical isolator and a clean-up filter.
