torus 532

The torus 532 laser is a high specification, green single frequency laser. Using intelligent electronics, the torus continually tracks its longitudinal mode position and ensures there is no mode-hop. The torus is available at 532 nm, with powers ranging from 50 mW - 750 mW making it ideal for applications such as holography, Brillouin scattering and Raman spectroscopy. The torus is a single longitudinal mode laser. 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.
