8.5 Solid-State Dye Lasers and Parameter Optimization
8.5.1 Effect of Pump Conditions on Solid-State Dye Laser Performances
Pump conditions including the kind and wavelength of pump source, repetition rate, pump intensity, pump pulse duration and its modes have significant influence on the laser performances of solid-state dye lasers, no matter how they are pumped longitudinally or transversely.
Up to now, the highest energy conversion efficiency obtained by flashlamp pumping was only 1%. [117]- [120] D. P. Pacheco et al. have demonstrated that the laser efficiency and lifetime of solid-state dye materials under us pump pluses were much lower than that under ns pulses due to higher triplet-state yield. [43] Other investigations showed that the laser lifetime of solid-state dye laser was longer and the laser threshold was low under ps pump pulse than those under ns pump pulses. [121]- [122] In short, a shorter pulse pump source is superior.
8.5.2 Cooling and Circulating Equipments of Solid-State Dye Lasers
Due to the movement of the media, different positions are excited alternatively. The time interval between two successive pump pulses onto a same position is long enough for the accomplishment of heat dissipation. So, the laser samples are cooled and circulated. The halt or change of the movement may leads to the cease of laser output.
By rotating P597 doped MTES-derived ORMOSIL, M. Canva et al. obtained 10 7 pulses of laser output at the repetition rate of 30Hz. [18] By rotating and translational moving...
