  2. 39 % of total conversion efficiency at pump level of 600mw 858nm is obtained experimentaily with our single - resonant, external ring frequency - doubler pumped by tr. sapphite laser at room temperature ( about 21. 50c ). the conversion efficiency is seriously limited by what is called " blura " ( blue light induced infrared absorption ) and thermal effects. yet, up to 137 mw of cw blue light at 429nm at pump level of 565 mw has been achieved and stabilized over a hour when the cavity is locked via pound - drever - hall ( pdh ) technique

    泵浦功率為600mw時,由於兩種效應「藍光導致紅外吸收( bliira ) 」和「熱效應( thermaleffects ) 」的嚴重影響,室溫下(約21 . 5 )獲得了39的倍頻轉換效率;採用邊帶鎖頻技術, 565mw的泵浦光獲得137mw的藍光輸出,在沒有外界強烈的干擾下可以鎖定1小時以上而不失鎖。
  3. The effects of multi - grating diffraction result in enhancement of the diffraction efficiency in two - beam interference experiments. with self - pumped phase - conjugate external cavity of ce : batio3 for the cw ti : sapphire laser, the frequency shift of the laser output due to the self - scanning effect was observed, which approve the possibility of the self - scanning tunable method

    同時位相共軛外腔還使得激光閡值由未加位相共軛腔時的4 . 7w下降到加位相共軛腔時的3 . 6w ,利用外腔理論對實驗結果進行了理論分析,理論計算結果和實驗結果基本符合。
