本論文中我們用以Cr4+:YAG 作為飽和吸收體的被動式Q 開關Nd:LuVO4 雷射去呈現實驗結果。在泵浦功率為5.47W 時,其平均的輸出功率等於0.63W 而穩定的脈衝列有著45KHz 的重複頻率,脈衝的半高寬為31ns 且峰值功率等於455W。當泵浦功率超過5.47W 後,時空不穩狀就會出現。不穩情形伴隨著脈衝分離還有衛星脈衝的產生。而實驗結果也展現了衛星脈衝產生的機制取決於多橫模互相的競爭。
In this work we used a passively Q-switching Nd:LuVO4 laser to present experimental results with a Cr4+:YAG saturable absorber. At a pump power of 5.47 W, the average output power was 0.63 W and the stable pulse train had a repetition rate of 45 KHz, a pulse width of 31 ns and a peak power of 455 W. When the pump power exceeded 5.47 W, spatial-temporal instability occurred. The instability accompanied the generation of pulse separation and a satellite pulse. The experimental results reveal that the mechanism of generation of the satellite pulse is governed by the multitransverse mode competition.
