Continuous Wave

Single Longitudinal Mode Lasers

Product Selection

The torus family offers a range of single longitudinal mode lasers with bandwidths below 1MHz. 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 TruLoQ™ 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. Tests have shown wavelength shifts of less than ±2pm over a 20°C shift in temperature and 0.3pm at constant temperature over a 30-minute test period. This technology eliminates mode drift and hop and creates a narrow line width laser with no sidebands.

This makes the torus family ideal for such applications as holography, interferometry, Brillouin scattering and any others where measurement time is over extended periods.
