Sapphire 488-nm Laser
Aug 2006
Coherent Inc.Request Info
SANTA CLARA, Calif., Aug. 23, 2006 -- The newest Sapphire laser from Coherent Inc. is a small-footprint OEM laser delivering 50 mW (CW) of output power at 488 nm. The Sapphire 50-mW laser is primarily intended for biomedical instrumentation, such as flow cytometry, drug discovery, genetic screening and confocal microscopy. This power level will deliver increased sensitivity, leading to faster throughput and/or higher signal-to-noise for these applications, without increasing the instrument size or operating budget, Coherent said.

This commonality allows easy implementation in next-generation instruments based on the Sapphire industrial standard without requiring redesign. These shared characteristics also permit system builders to choose power levels from 10 to 50 mW using a single laser engine platform.

Until the advent of the Sapphire laser platform, applications for 488-NM output had to rely on power-hungry, air-cooled argon lasers. The all-solid-state Sapphire provides the advantages of smaller size, greater electrical efficiency, lower heat dissipation and a substantially longer lifetime. Coherent said the result is a reduction in cost of ownership over argon laser technology, making Sapphire suitable (and even a retrofit option) for low- and medium-power applications in bioinstrumentation and semiconductor inspection.

flow cytometry
A method of measuring the characteristics of microscopic particles, usually cells, as they flow in a fluid stream through a beam of light. Particles may be stained with fluorescent dye and the fluorescence detected via laser illumination.
