DORTMUND, Germany, May 30, 2012 — Single-emitter diode lasers with spectral widths from 420 to 470 nm that output up to 2 W are becoming popular in lithography, in structuring of flat panel displays and in measuring technology such as particle analysis.
The blue semiconductor laser emitters’ Blu-Ray disk’s light sources work with a very low output and actually emit violet light at 405 nm. LIMO Lissotschenko Mikrooptik GmbH has developed micro-optics for true blue single-emitter diode lasers.
The technology focuses the beam with precision on an area measuring ~40 × 40 µm. Micro-optics technology is suited for pumping solid-state crystals and for fiber coupling.
The low-cost technology requires only one micro-optics device to focus the blue laser. Two versions are available for diode lasers with or without housing.
