2-Step Pumped Ylftm Blue Up-Conversion Laser
Abbreviated Journal Title
J. Phys. IV
Several fluoride and oxide Tm and (Tm, Yb) doped crystals such as YLF, GLF, YAG, and YAlO3 were tested for pulsed lasing at the 1D2 -- > F-3(4) transition (453 nm blue) at room temperature under two step pumping by a Ti:sapphire and a dye laser. Laser operation was obtained for the fluoride crystals. The input-output curves exhibit a saturation effect of emission with respect to both pump lasers. This can be explained by a depletion of the H-3(6) ground state of Tm3+ and the competition between the excited state absorption from the H-3(4) intermediate level and the mechanisms depopulating this level.
