Abstract

Cladding waveguides are fabricated in Yb,Na:CaF2 crystal by applying femtosecond laser inscription. Waveguide properties are investigated in terms of guiding behaviors and confocal micro-Raman characterizations. In addition, under 946 nm excitation, visible cooperative up-conversion emissions at 478 nm induced by Yb3+ ion pairs are observed while other visible bands are detected owing to the impurities of Er3+ and Tm3+ ions.
