Klastech-Karpushko Laser Technologies will introduce the Concerto 442nm laser at Photonics West 2010.
Targeting the He-Cd gas-laser market, this DPSS laser provides continuous wave (CW) output at 442nm.
The Concerto provides significant second harmonic conversion efficiency improvements over traditional DPSS laser architectures.
The new laser is smaller than the traditional He-Cd (less than 200mm long compared with 700mm for a similar powered gas laser).
The solid state design also leads to a significant reduction in thermal and mechanical issues, resulting in a more stable laser platform that boasts <10urad/C beam-pointing stability.
Users no longer have to provide for periodic re-melting as its power remains stable until end of life, which is a projected 10,000 hours.
In common with all other Klastech lasers, the Concerto exhibits silent running (less than 0.5 per cent rms noise), provides diffraction-limited output beams with M2 better than 1.05 and achieves long-term power stability of less than two per cent.
The underlying laser technology inherently produces pitch-perfect single frequency performance and with a line width less than 1MHz delivers a coherence length in excess of 100m.
Currently the company is taking advance orders for 20mW versions, with higher powers planned for 2010.
Applications include holography, stereo lithography, spectroscopy, CD mastering and diffraction-grating fabrication.
