The torus family offers a range of single longitudinal mode lasers with bandwidths below 1 MHz. These are ideal for applications such as high resolution Raman spectroscopy, holography and interferometry that benefit from the long coherence length.
Unique in the marketplace, the torus family all benefit from active mode locking technology. This advanced internal software maintains the performance of the output beam, ensure a stable frequency output across long measurements and wide temperature fluctuations. This technology eliminates mode drift and hop and creates a narrow linewidth laser with no sidebands.
