Description

The CRL-CLxxxx-S with low intensity noise and high long-term stability

The CRL series SLM diode pumped solid state lasers provide spectral line widths in the sub pm range resulting into coherence lengths of several 10 m. The series is characterized by a low intensity noise and a high long-term stability. The intensity noise from several Hz up to the MHz range is given to less than 1%. The long-term stability is better than 2% and can be improved to less than 0.25% as an ultra-stable option if needed. The available wavelengths cover the range from 473 nm to 1340 nm with optical powers between 5 mW and 1 W. The beam quality is almost diffraction limited with M2 values less than 1,2 or 1,1. As options there are fiber couplings for singlemode and multimode fibers available.
