The Rumba 05-01 CW single-frequency DPSS laser from Cobolt AB (Stockholm, Sweden) operates at 1064 nm with up to 2 W CW output power in a TEM₀₀ beam (M2 <1.1) for high-resolution Raman spectroscopy, interferometry and optical tweezers experiments. A proprietary cavity design provides typical low noise performance of <0.1% rms (over 20 Hz to 20 MHz and over 10° to 40°C) and a narrow spectral linewidth of <1 MHz. Proprietary HTCure technology in a 115 × 70 × 45 mm package allows withstanding of multiple 60 G mechanical shocks in operation, as well as extreme temperatures to >100°C.

PRESS RELEASE

Cobolt RumbaTM: Ultra-low noise 1064 nm

Cobolt AB, Swedish manufacturer of high performance DPSS lasers, announces the release of a new wavelength on the ground breaking single-frequency 05-01 platform released in 2009. The new Cobolt RumbaTM operates at 1064 nm with up to 2 W CW output power and is perfectly suited to demanding applications such as high resolution Raman spectroscopy, interferometry and optical tweezers experiments. Available on the same platform is also the Cobolt ZoukTM with 10 mW CW at 355 nm and the Cobolt SambaTM with up to 1000 mW CW at 532 nm.

The Cobolt Rumba™ 05-01 is a continuous-wave single-frequency DPSS laser operating at 1064 nm with up to 2 W output power in a perfect quality TEM00 beam (M2<1.1). A new proprietary cavity design provides ultra-low noise performance of typically <0.1% rms (over 20 Hz-20MHz and over 10-40°C) and a narrow spectral linewidth of <1MHz.

The laser is manufactured using Cobolt’s proprietary HTCureTM Technology in a compact and hermetically sealed package (115x70x45 mm), which provides a very high level of immunity to varying environmental conditions and exceptional reliability. Lasers built using the HTCureTM 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 supplied with a compact controller (CDRH or OEM) which can be remotely accessed for operation and monitoring of the laser system over digital (RS-232) or analog interfaces.
