【摘要】 本文报道新研制成功的GW大功率激光系统。使用双普克尔盒电光开关从混合型CO₂激光振荡器中削出的激光窄脉冲通过一台三节双光程TEA CO₂激光前置放大器和一台两节TEACO₂激光前置放大器、一台大口径TEA CO₂激光放大器,最后通过一台电子束控制CO₂激光放大器放大后输出。激光输出功率高达3.2×10⁹W,脉宽为4ns。更多还原

【Abstract】 A GW level high power CO2 laser system has been developed. A short laser pulse is cut out by a double Pockels eellelectro-optical shutter from a hybrid CO2 laser oscillator and amplified by a three-stage dual-path TEA preamplifior, a two-stage TEA preamplifier, a large aperture TEA amplifier and an electron beam controlled terminal amplifior. All parts of the laser system are controlled with a control system. The laser output power is up to 3.2×l09 watts, and the laser pulse width is 4ns.更多还原
