“…The singlepulse energy E and the peak power P are determined by the average output power P A , the pulse repetition rate F and pulse duration τ . Using the equations E = P A /F and P = E/τ [29], single-pulse energy E and peak power P are calculated. The dependences of single pulse energy and Figure 5 (online color at www.lphys.org) The peak powers versus the incident pump power peak power as functions of the incident pump power are plotted in Fig.…”

Abstract:A diode-end-pumped AO Q-switched YVO 4 / Nd:YVO4 composite crystal laser is demonstrated in this paper. With a comparative simple cavity, the laser can generate short pulse duration and high peak power by optimum design. The shortest pulse width of 9.5 ns and the maximum average output power of 10.12 W are obtained at the repetition rate of 90 kHz, corresponding to an optical conversion efficiency of 37.5%. A 4.2-ns pulse with 2.9-mJ pulse energy and 691.4-kW peak power has been achieved under 20 W incident pump power at 1 kHz.Pulse trace for the 1064-nm YVO 4 /Nd:YVO 4 laser with 50% output coupler at a repetition frequency of 1 kHz

By considering the AO switch as a low speed switch and the AO turnoff time including the transit time of the acousticwave and the electronic turnoff time as well as the Gaussian spatial distribution of the intra-cavity photon density, the coupled equations of a Laser-diode pumped actively Q-switched Nd:YVO 4 laser with acoustic-optic modulator are given. By changing the position of AO in the cavity for changing the transit time of the acoustic-wave, the effect of the AO transit time on the characteristics of the output Q-switched pulse is obtained. It is show that the longer transit time leads to the wider pulse duration. In the experiment, a laser-diode-pumped actively Q-switched Nd:YVO 4 laser with acoustic-optic modulator is realized, and the experimental results are in fair agreement with the numerical solutions.

Actively Q-switched laser performances of composite and conventional Nd:YVO4 crystals were investigated and compared with dierent Nd-doped concentrations of laser media and dierent repetition rates of electro-optic modulator. Both continuous-wave and actively Q-switched operations were realized experimentally. At an incident pump power of 7.69 W, the shortest pulse duration of 6.5 ns was obtained by the composite Nd(0.1 at.%):YVO4/Nd(0.3 at.%):YVO4/Nd(0.8 at.%):YVO4 crystal at the repetition rate f = 2 kHz. However, the composite Nd(0.1 at.%):YVO4/Nd(0.5 at.%):YVO4/Nd(1.0 at.%):YVO4 laser achieved the maximum average output power of 687 mW at f = 10 kHz and the largest single pulse energy of 144 µJ at f = 2 kHz. Power saturation of the conventional Nd:YVO4 crystal was shown during experiment, while no power saturation was observed on the composite Nd:YVO4crystals, showing good thermo-mechanical performances.
