Swedish diode-pumped solid-state laser manufacturer Cobolt has announced a modulated dual-line light engine optimised for high-end Optogenetics research applications.
This version of the Cobolt Dual Combiner offers two emission wavelengths for light-activated proteins, 473nm (up to 50mW) and 594 nm (up to 100mW). Through the integration of a silent SRS shutter the output beam can be modulated at up to 100Hz with a very short rise time of <350μs. This can also maintain a three per cent power stability and an RMS noise of <0.3 per cent.
Each line can be individually addressed through a software application provided with the lasers or through RS232/USB communication. The modulated Dual Combiner is also available with any other 2-line combination of the Cobolt 04-01 series lasers.
