受激布里渊散射相位共轭镜产生高质量短脉冲XeCl激光
Phase-Conjugate Mirror for Generation of High Quality and Short Pulse XeCl Laser
摘要
利用受激布里渊散射(SBS)相位共轭镜改善XeCl激光光束质量和压缩脉冲宽度,给出了脉宽与泵浦能量、焦点位置的关系。光脉冲宽度从50ns压缩到17ns,光束发散角也减小到原来的1/3,散射光功率密度也较泵浦光得到了提高。
Abstract
Stimulated Brillouin scattering (SBS) phase-conjugate mirror was used to produce XeCl laser beam of good optical quality and short time duration. The amplified phase-conjugate beam duration could vary from 50 ns to 17 ns, by changing the pump pulse energy or the depth of the lens focus into the SBS medium. The spatial quality of this beam was improved.
