Laser Quantum torus 660

torus

The torus 660nm laser provides true single longitudinal mode (SLM) with a coherence length in excess of 100m and a bandwidth of <1MHz. Using active mode locking technology to stabilise the laser cavity the wavelength stability is measured to be <2pm 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.
