Torus Laser
Description
The torus 532 system is a single longitudinal mode laser. Using digital electronics, the 532 nm beam is locked in frequency so that no mode-hops occur. Control of the laser can be accessed through a dedicated RS232 port on the PSU. The unique patented travelling-wave cavity results in an ultra-low noise output.
