Cobolt ABRequest Info
Cobolt AB has introduced 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 noise performance of <0.1% rms over 20 Hz to 20 MHz and over a temperature range of 10 to 40 °C. The laser is manufactured using proprietary HTCure technology in a hermetically sealed package measuring 115 x 70 x 45 mm.

1. A bundle of light rays that may be parallel, converging or diverging. 2. A concentrated, unidirectional stream of particles. 3. A concentrated, unidirectional flow of electromagnetic waves.
In a laser, the optical resonator formed by two coaxial mirrors, one totally and one partially reflective, positioned so that laser oscillations occur.
The study and utilization of interference phenomena, based on the wave properties of light.
Raman spectroscopy
That branch of spectroscopy concerned with Raman spectra and used to provide a means of studying pure rotational, pure vibrational and rotation-vibration energy changes in the ground level of molecules. Raman spectroscopy is dependent on the collision of incident light quanta with the molecule, inducing the molecule to undergo the change.
