Cobolt Dual Combiner

Cobolt, Swedish manufacturer of high performance DPSS lasers, has expanded their product offering for compact visible laser sources by releasing of the Cobolt Dual Combiner.

This device provides alignment-free combination of any two lines in Cobolt’s broad range of visible lasers in one compact package. Built on a compact and stable platform with optimised thermo-mechanical properties, the Cobolt Dual Combiner provides a permanently aligned beam overlap. The very small dynamical tolerances of the beam overlap (<20µrad/°C), combined with a robust and compact platform make adjustment uneccessary. The device can be used for drop-in replacement of gas lasers or as a way to expand the wavelength offering of existing light-engines, e.g for confocal micriscopy, without the need for any re-design. The foot-print of the device is only 190 x 65mm, and the two laser lines can be addressed individually through RS-232 communication. Examples of attractive line-combinations that can be offered with the Cobolt Dual Combiner are: 491+515nm, 491+457nm, 491+561nm or 561+594nm.

The Cobolt visible lasers are continuous-wave DPSS lasers operating at fixed wavelengths of 457, 473, 491, 515, 532, 561 or 594nm, and with output power levels of up to 300mW. Built into a hermetically sealed compact package using the proprietary HTCureTM technology for extreme robustness, the Cobolt visible lasers are single longitudinal mode lasers with low noise (<0.3 per cent rms), narrow spectral line width (typically <30 MHz) and exceptionally high beam quality (M2<1.1). The Cobolt visible lasers are based on proprietary PPKTP frequency conversion technology, for optimum flexibility and efficiency.
