摘要
We report on the experimental results of a continuously diode-laser pumped Nd:YAG laser, operating at 1064 nm and repetitively Q-switched by a Cr4+:YAG solid-state saturable absorber. End-pumping the Nd:YAG with a 10-W fiber-coupled diode-laser we could either optimize the energy or the average output power, depending on the choice of the saturable absorber and the output coupler, The maximum energy was approximate to 200 mu J in single TEM00, 17 ns pulses at 6 kHz, whereas a maximum average power of approximate to 2 W with 32-ns pulses at 20 kHz was obtained. We also present preliminary results of a repetitively Q-witched Nd:YVO4 laser at 1064 nm, The repetitive Q-switching operation is described by an improved model, which accounts for the behavior of both the active medium and the solid-state saturable absorber. The results of the model agree fairly well with the experimental data. Experimental results of second harmonic conversion are also reported and interpreted using a depleted pump model.
