BioPhotonics
Oct 2012Laser Quantum UK has launched the tau 671-nm laser with a compact mono-block design that makes it suitable for OEM integration.
It outputs up to 50 mW with a stable TEM
00 diffraction-limited beam. The single-transverse-mode continuous-wave red laser is used in Raman and fluorescence spectroscopy, and in DNA sequencing.
Features of the hermetically sealed laser include a permanently aligned cavity, noise <1% rms, RS-232 control, an ~100-GHz bandwidth, beam divergence <1 mrad, M
2 <1.2, pointing stability <10 μrad and a polarization ratio >100:1. Polarization direction is horizontal, coherence length is ~3 mm, beam angle is <2 mrad, and operating temperature is from 22 to 37 °C.
