Abstract

Upconversion signals in the wavelength region 407–550 nm were emitted from CaF2:Eu3+ under 578.7 (or 589.2-) nm dye-laser excitation. The intensities of the upconversion signals were enhanced 25× under double-resonance excitation by a 589.2-nm dye laser and a 703.6-nm Ti:sapphire laser. Excited-state absorption cross sections were estimated for some of the transitions.
