MHz repetition rate femtosecond radially polarized vortex laser direct writing Yb:CaF2 waveguide laser operating in continuous-wave and pulsed regimes
In this paper, we report the use of femtosecond radially polarized vortex laser with MHz repetition rate for direct writing of cladding waveguides (WGs) and realization of waveguide laser oscillations in ytterbium-doped calcium fluoride crystal. The negative refractive index modification in Yb:CaF2...
