摘　　要：本文报道了在两种结构的多镜复合腔中CuBr激光器的纵模淬灭现象,并得到了重复频率几倍于基频纵模间隔的多重锁模脉冲串,最高重复频率可达440MHz.实验结果表明,通过调整复合腔的结构参数,可以在不缩短增益介质长度的条件下,实现CuBr激光多重锁模脉冲高重复频率的大范围调节.The phenomena of longitudinal mode quenching in a CuBr laser with two types of multiple-mirror compound resonators are reported. The multiple mode-locking pulse trains at a repetition rate equal to a multiple of the fundamental longitudinal mode spacing have been obtained. The highest repetition rate is up to 440 MHz. The experimental results indicate that the mulptiple mode-locking pulses at high and wide-range tunable repetition rate in CuBr laser can be generated by adjusting the structure parameters of the compound resonators,without shortening the length of the active medium.
