摘　　要：利用高效LD端泵浦与耦合技术对Nd：YVO4介质进行激励，采用声光调Q，实现了从10kHz-1．5MHz频率段连续可调的1064nm高重频稳定激光输出。通过增益最优化动态程控技术、精确智能温控技术以及大面积铜热沉与循环水冷相结合的方法，消除了脉冲不稳定现象，使全频段的激光脉冲输出波形达到最佳，完成了激光器的工程化测试与封装，激光系统具有良好的温度适应性和抗震性能。A novel LD end pumping and coupling technic is employed to stimulate a Nd：YVO4 crystal rod, with an acousto-optical Q-switch used simultaneously, producting a steady 1 064 nm laser output with frequency tunable from 10 kHz to 1.5 MHz. By making use of methods as programmed dynamic gain optimization control,precise intelligent thermal management and combination of cupreous heat sink and cooling water circulation, the pules instability is eliminated,leading to the optimigation of the laser pulse output shape in the whole frequency range. Industrialized test and encapsulation are carried out to ensure good temperature suitability and anti-vibration performance.
