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.
