摘要
介绍了基于啁啾脉冲放大技术的20TW全钛宝石超短脉冲激光装置的研制.该装置的主放大器采用全像传递的空间四程放大构型,可以保持良好的近场分布和提高能量转换效率.主放大器的钛宝石晶体为φ30mm×15mm,6台调Q倍频的YAG激光器泵浦.压缩后脉宽50fs,能量1J,峰值功率可达20TW,聚焦功率大于3×1018W/cm2.
Abstract
The design and characterization of a Ti:sapphire high-intensity laser system is presented. A spatial four-pass image-delayed amplifier, which can output good quality beam, is employed in the system. The system is demonstrated in order to reach the intensity in excess of 3×1018W/cm~2 for ultra-intensity field experiments. In order to decrease the effects of gain narrowing, an acousto-optic programmable dispersive filter is applied after the femtosecond oscillator.
