【摘要】 在Ｒｉｇｒｏｄ理论基础上建立准分子激光非稳腔稳态理论模型，通过测量不同泵浦条件下七种输出耦合的平行平面腔的输出光强，给出小信号增益系数ｇ＿０，非饱和吸收α以及饱和参量Ｉ＿ｓ，由此通过非稳腔稳态理论推算出不同放大率Ｍ的虚共焦非稳腔的输出光强Ｉ＿（ｏｕｔ），与实验结果基本吻合。更多还原

【Abstract】 On the basis of Rigrod’S theory,we have developed a steady-state theory of unstableresonator for excimer laser.The small-Signal gain g₀,unsaturable absorption coefficient αandsaturable intensity I_s are estimated by measuring the output intensity of parallel-plane oscillatorswith seven output couplings under different pump conditions. Thus,the output intensity I_out ofpositive-branch confocal unstable resonators as a function of magnification M are obtained throughunstable resonator steady-state theory.The calculated parameters of unstable resonator are inagreement with the experimental results.更多还原
