摘要
室温下利用337nm脉冲激光照射着色LiF晶体,有效地将F_2心转变成F_2^+心,其浓度高于10^(16)cm^(-3)。利用消象散三镜折叠腔,研究了LiF晶体F_2和F_2^+心激光特性。实际工作表明,利用氮分子激光作为处理光束,可获得较长时间稳定的F_2^+心激光输出。
High density (greater than 10^(16)cm^(-3)) F_2^+ centers can be effectively created in a colored LiF crystal irradiated with a nitrogen laser (λ=337nm) at room temperature.The performance of F_2 and F_2^+ centers LiF crystal laser has been investigated by using a three-mirror optical cavity to compensate the astigmation.The experiments show that the stable F_2^+ center laser operation can be obtained by using a nitro- gen laser as a processing beam.
