torus 532nm - Green Single Longitudinal Mode (SLM) laser with active mode locking. 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.
torus 660nm – Red SLM laser with active mode locking
The torus 660 nm laser provides true single longitudinal mode (SLM) with a coherence length in excess of 100 m and a bandwidth of <1 MHz. Using TruLoQ™ active mode locking technology to stabilise the laser cavity, the wavelength stability is measured to be <2 pm over 20°C ambient temperature shift and mode hop is eliminated. The torus 660 is ideal for applications such as interferometry, Raman studies and holography.
