| 摘 要： | 报道了掺钛蓝宝石晶体激光放大实验研究，实验中得到最大的单程放大和双程放大增益分别为１４．７６和２６．３１，对应双程放大的增益系数为１．８１ｃｍ－１，并由此推算出掺钛蓝宝石晶体的增益截面为２．７４×１０－１９ｃｍ２，饱和能量密度为０．９３Ｊ／ｃｍ２．并给出不同的泵浦能量密度所对应的最佳放大介质长度。实验表明小信号近似下，放大增益只与泵浦功率密度有关．与注入种子能量无关。实验还测量了掺钛蓝宝石晶体对不同波长种子光的放大增益。

| Abstract: | A small-signal single-pass power gain of 14.76 and double-pass power gain of 26.31 have been measured for a Ti:sapphire amplifier. The results correspond to thesmall-signial gain coefficient being 1.81 cm-1 and the gain cross section being 2.74×10-19 cm2. The small-siginal gains for different wavelengths have been obtained. Thesaturation fluence and optimum length of Ti:sapphire have been calculated. |
