Compact, CW UV DPSS laser for flow cytometry, confocal microscopy, HCA from Cobolt AB

Cobolt Zouk, from Cobolt AB (Stolna, Sweden) is a continuous wave (CW) diode-pumped solid-state (DPSS) laser that operates at a fixed wavelength of 355 nm (ultraviolet) with an output power of 10 mW. It features a compact (80x60 mm footprint), hermetically sealed package using Cobolt's proprietary HTCure technology. Zouk promises a power-efficient alternative to the Ar/Kr-ion UV lines and quasi-CW UV lasers in demanding fluorescence applications such as flow cytometry, confocal microscopy, and high content analysis (HCA). The 355 nm wavelength is particularly helpful for efficient excitation of staining agents DAPI, Hoechst 33342, and Indo-1 in cell biology and DNA and Ca2+ analysis. The laser comes with an ultra-compact controller (CDRH or OEM) that can be remotely accessed for operation and monitoring via USB or analog interfaces.

Cobolt Zouk-the world's first compact CW 355 nm DPSS Laser!

Cobolt AB, Swedish manufacturer of low-noise DPSS lasers, reveals ground-breaking solid-state laser technology in the UV range. The Colbolt Zouk is the world's first truly compact, true CW DPSS laser at 355nm and will be demonstrated at the BiOS/Photonics West shows in San Jose, January 24-29, 2009. With 10 mW output power and a perfect TEMoo beam, the Cobolt Zouk is a compact and power efficient alternative to the Ar/Kr-ion UV lines and quasi-CW UV lasers in applications such as fluorescence-based bioanalysis.
