Abstract

In this invited talk we report on the CaNaPy facility laser being developed at ESO, in collaboration with MPBC and Toptica projects. The MPBC breakthrough of high power narrow band Raman Amplifiers based on the ESO patented technology has allowed to demonstrate and commission, at the time of this writing, a 63W CW laser with the same optical beam and functional properties as the commercial 22W CW 589nm Toptica-MPBC lasers. To avoid saturation effects due to the high irradiance at the mesospheric sodium layer, Toptica projects has developed and integrated remarkable frequency chirping capabilities, on a laser architecture which remains similar to the commercial 22W version. In the talk, besides the presentation of the design and of the test results, there will be an outlook on commercial availability, further laser power scalability and other emerging developments, for applications related to astronomical adaptive optics as well as space awareness and satellite communications.
