摘　　要：本文用重复率为10Hz、调Q、Nd∶YAG激光器的二倍频输出泵浦四级染料放大器,把从对撞脉冲锁模(CPM)环形染料激光器中产生的43fs的光脉冲能量放大到100μJ,脉冲宽度为125fs,峰值功率为800MW,在用一组四棱镜系统对放大的光脉冲进行群速度色散补偿以后,得到了宽度为70fs的放大光脉冲输出,峰值功率达GW。We constructed experimentally the four-stage dye amplifier pumped by a Q-switched frequence-doubled Nd:YAG laser with repetition rate of 10 Hz. It amplified 43 fs optical pulses to energy of 100μJ and pulsewidth of 125 fs. Optical pulses with pulsewidth of 70 fs and peak power of 1 GW has been generated using a four- prism sequence compressor.
