Cobolt AB has released a new wavelength on the single-frequency 05-01 platform released in 2009. The Cobolt Rumba diode-pumped solid-state (DPSS) laser operates at 1064 ±0.6 nm with up to 2 W of continuous-wave output power and is suited to applications such as high-resolution Raman spectroscopy, interferometry and optical tweezers experiments. The single-frequency laser delivers a TEM00 beam with M2 <1.1. A new proprietary cavity design provides a narrow spectral linewidth of <1 MHz and typical ultralow-noise performance of <0.1% rms over 20 Hz to 20 MHz and over a temperature range from 10 to 40 °C. It is manufactured using proprietary HTCure technology in a compact and hermetically sealed package measuring 115 x 70 x 45 mm, which provides good reliability and a high level of immunity to varying environmental conditions.
