The laser system in our experiments consists of a Nd:YAG oscillator and three Nd:glass amplifiers with diffraction-limited output beams. Crystals for frequency doubling are KDP and KD*P. When unfocused collimated laser beams were used in frequency doubling, a maximum energy, conversion efficiency of 65% has been obtained,the corresponding peak power conversion efficiency was about 84%. In the case of low laser power, by means of cylindrical focusing laser beams, energy conversion efficiencies were increased by a factor of 8 to 30 with a maximum conversion efficiency of 64%.

The nonlinear two-photon absorption of Nd ions in Nd-doped laser glasses was studied with single picosecond laser pulses from a mode-locked Nd glass laser.With the aid of ex- periments and theoretioal oaleulations,we obtained the cross section for two-photon absor- ption of Nd ions σ=(6.16±1.1)×10~(-33)cm~4/W,the nonlinear absorption coefficient r= (1.65±0.29)×10~(-12)cm/W and profiles for the function relationship between the optical intensity and the transmissivity.The peak output intensity for Nd glass amplifiers is limi- ted by two-photon absorption.It was determined experimentally that the maximum peak intensity of the amplifiers is I_(max)=(4.15±0.73)×10~(10)W/cm~2.

In this paper a way of generating high efficiency and diffraction-limited dye laser beam is proposed. In this dye laser, Rhodamine 6G solution in alcohol is pumped by counterpropagating pumping beams in four-wave mixing. The 5320A laser radiation from second harmonic of the output of a Nd:laser system consisting of a Q-switched Nd: YAG oscillator and Nd:glass amplifiers is used as the pumping source. The Rhodamino 6G solution is used as both the active medium of the dye laser and the nonlinear medium for four-wave mixing. The concentration of the Rhodamine 6G solution in alcohol ia about 5×10-5 mole. Using pumping intensity of about 5×106 W/cm2, the energy conversion efficiency of the pumping beam to dye laser beam is about 50%, and the beam divergence of the laser output is near diffraction-limited. The good quality of the output beam of the new type dye laser is analysed theoretically.
