SOLNA, Sweden, July 2, 2010 — Cobolt AB has released a new wavelength on the single-frequency 05-01 platform released in 2009. The Cobolt Rumba diode-pumped solid-state 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.
The laser is manufactured using proprietary HTCure technology in a compact and hermetically sealed package measuring 115 × 70 × 45 mm, which provides good reliability and a high level of immunity to varying environmental conditions. Lasers built using the technology have been shown to withstand multiple 60-g mechanical shocks in operation without any sign of degraded performance. They can be exposed to extreme temperatures of >100 °C and are insensitive to pressure and humidity.
Full angle beam divergence is <1.6 mrad, beam diameter at aperture is 1 mm, long-term stability over 8 h is <2%, typical beam pointing stability is 5 µrad/°C, vertical polarization ratio is >100:1, and total system power consumption is typically <30 W.
The laser is supplied with a compact CDRH or OEM controller that can be remotely accessed for operation and monitoring of the laser system over digital RS-232 or analog interfaces.
