  • Cobolt Zouk 355 nm 20mW continuous-wave single-frequency DPSS laser

The Cobolt Zouk is a continuous-wave (CW) single-frequency DPSS laser operating at 355 nm in a perfect quality TEM00 beam (M2<1.1) and with 10 or 20 mW output power.

A proprietary laser cavity design provides ultra-low noise performance of typically <0.2% rms (over 20 Hz-20MHz and over 10-40ºC), a narrow spectral linewidth of <1MHz and immunity to optical feedback. The laser is available with 10 or 20mW output power and is perfectly suited to applications such as fluorescence analysis with e.g Hoecht Blue Indo-1 or DAPI for DNA content analysis or calcium imaging in flow cytometry and confocal TIRF microscopy, as well as Raman spectroscopy on semiconductors.

The laser is manufactured using Cobolt's proprietary HTCure Technology in a compact and hermetically sealed package (115x70x45 mm), which provides a very high level of tolerance to varying environmental conditions and exceptional reliability. Lasers built using the HTCure Technology have shown to withstand multiple 60G mechanical shocks in operation without any sign of degraded performance. They can be exposed to extreme temperatures (>100°C), and are insensitive to pressure and humidity.

The laser is now available on the 05-01 Series single frequency platform and is supplied with a compact controller (CDRH or OEM) and free software for operation and monitoring of the laser system using RS-232 or USB communication.

Available on the Same Platform is also:
o Cobolt Calypso with up to 200mW CW at 491nm
o Cobolt Samba with up to 1.5W CW at 532 nm
o Cobolt Jive with up to 500mW CW at 561 nm
o Cobolt Flamenco with up to 500mW CW at 660 nm
o Cobolt Rumba with up to 3W CW at 1064 nm
