The new CRESCENDO DPSS ruby laser from KLASTECH-Karpushko Laser Technologies GmbH (Dortmund, Germany) is available in 100mW and 150mW versions with plans to increase its power output to 500mW.

The unit produces a pitch perfect single longitudinal frequency (<1MHz line width) with a coherence length in excess of 100m. Optically the laser exhibits near perfect Gaussian beam performance coupled with <10µrad/°C beam pointing stability and exceptional noise figures down to <0.05% rms.​
