摘　　要：探讨了双线纵向激励F2+型色心激光器在不同泵浦光、辅助光和振荡光的束腰半径之比下的增益特性．研究表明，为获得较高基模比例的激光输出和较高的泵浦光利用效率，泵浦光的束腰半径应选择略小于振荡光的束腰半径，辅助光的束腰半径应与泵浦光的束腰半径近似相等．A study is made on the gain characteristic of two-beam longitudinally excited F2+ type color centerlaser under pumping beam and auxiliary beam and oscillatory beam in different ratio. In order to obtain alaser output of higher TEM00 mode and a pumping beam of higher utilized effiency, the waist radius ofpumping should be smaller than that of oscillatory beam; and the waist radius of auxiliary beam should approach to that of pumping beam.
