英文摘要 | a double-sided liquid cooling nd: yag disk oscillator working at a pump repetition rate of 20 hz is demonstrated. the output energy of 376 mj is realized, corresponding to the opticaloptical efficiency of 12.8% and the slope efficiency of 14%. the pump pulse width is 300 mu s and the laser pulse width is 260 mu s. instead of being a damped signal, the output of laser comprises undamped spikes. a periodic intra-cavity loss was found by numerical analysis, which has a frequency component near the eigen frequency of the relaxation oscillation. resonance effect will induce amplified spikes even though the loss fluctuates in a small range. the shark-hartmann sensor was used to investigate the wavefront aberration induced by turbulent flow and temperature gradient. according to the wavefront and fluid mechanics analysis, it is considered that the periodic intra-cavity loss can be attributed to turbulent flow and temperature gradient. |
