Photonics Tech Briefs
Product of the Month
May 1999

TuiOptics GmbH, Munich, Germany introduces what it calls the first direct blue external cavity diode laser (ECDL). TuiOptics, which is represented in the U.S. and Canada by Polytec PI, Auburn, MA, offers an ECDL with single-mode transverse and longitudinal output in the 400-nm region. Center wavelength can be chosen in the range between 395 and 405 nm, and the laser is coarsely tunable over more than 2 nm. TuiOptics says that the mode-hopping-free tuning of a few GHz makes the laser usable in high-resolution spectroscopy and the research community.
