  • Samba 05-01 532-nm Laser
May 2010
Cobolt ABRequest Info
SOLNA, Sweden, May 24, 2010 — The Samba 05-01 platform, manufactured by Cobolt AB for single-frequency and ultralow noise continuous-wave lasers, generates up to 1 W of CW output power at 532 nm from a compact package.

Applications include high-resolution Raman spectroscopy, interferometry, flow dynamics, high-speed fluorescence analysis and laser pumping on an industrial level.

The diode-pumped solid-state laser delivers a TEM00 beam with M2 of <1.1. A new proprietary cavity design provides typical noise performance of <0.1% rms from 20 Hz to 20 MHz, with an operating temperature range from 10-40 °C and a narrow spectral linewidth of <1 MHz. The use of the company’s periodically poled potassium titanyl phosphate frequency conversion technology in the laser design also provides high power efficiency. The system consumes less than 66 W.

The laser is manufactured using proprietary HTCure technology in a hermetically sealed package measuring 115 × 70 × 45 mm, which provides good reliability and immunity to varying environmental conditions. It can withstand multiple 60-g mechanical shocks without any sign of degraded performance. It can be exposed to extreme temperatures of >100 °C and is insensitive to pressure and humidity. The laser delivers good long-term wavelength stability of <2 pm and an ultraclean spectrum.

The laser is supplied with a compact controller (CDRH or OEM) that can be remotely accessed for operation and monitoring of the system over digital RS-232 or analog interfaces.

A physical variable that is proportionally similar to another variable over a specified range. An analog recording contains data that is similar to the source.
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.
