The power and beam quality behavior of second-Stokes KGW and diamond external cavity Raman lasers at pump powers up to 40 W has been investigated. Severe thermally-induced effects are evident in the KGW Raman laser at high power levels whereas for diamond these are negligible. The diamond Raman laser generated a maximum of 16 W with conversion efficiency and output beam brightness 2.2 and 13 times...
Crystal Raman lasers offer a possibility to build robust coherent light sources at new specific wavelengths for applications across many fields of science and technology. To date, the clear majority of studies have been based on pump lasers which are multi-longitudinal mode such as standing-wave cavity Nd and Yb lasers [1]. In such cases the Raman laser spectrum is also multimode with broadening contributions...
We report measurements of parameters important to Raman laser design for single crystal synthetic diamond. Raman laser operating space is assessed as functions of the pump wavelength, temporal format and design architecture.
