Cobolt has released the Cobolt Samba, a new platform for single-frequency and ultra-low noise CW lasers, capable of generating up to 1W CW output power at 532nm from a very compact package.
The Samba brings advanced scientific applications, such as high resolution Raman spectroscopy, interferometry, flow dynamics, high-speed fluorescence analysis and laser pumping, to an industrial level. Also available on the same platform is the Cobolt Zouk with 10mW CW at 355nm.
The Cobolt Samba 05-01 is a continuous-wave single-frequency DPSS laser operating at 532nm with up to 1W 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 per cent rms (over 20Hz-20MHz and over 10-40°C) and a narrow spectral linewidth of <1MHz. The use of Cobolt's PPKTP frequency conversion technology in the laser design also provides unmatched power efficiency. The full laser system consumes less than 66W power.
The laser is manufactured using Cobolt's HTCure Technology in a compact and hermetically sealed package (115 x 70 x 45mm), which provides a very high level of immunity to varying environmental conditions and exceptional reliability. Lasers built using the HTCure 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 single-frequency feature of the laser, combined with the high output power, an excellent long-term wavelength stability (<2pm) and an ultra-clean spectrum makes the Cobolt Samba 05-01 perfectly suited for very demanding applications such as high-resolution Raman spectroscopy, interferometry, flow dynamics, high-speed fluorescence analysis and laser pumping. The compact size and robust package of the laser opens up new possibilities to bring advanced scientific applications to an industrial level.
