摘要
分析了啁啾脉冲在钛宝石再生放大器中的能量增益与泵浦光及信号光光束口径的关系。并用不同能量的调Ｑ倍频ＮｄＹＡＧ激光器的５３２ｎｍ光为泵浦光，测量了２ＴＷ钛宝石激光系统中钛宝石再生放大器在无注入信号脉冲时和有注入信号脉冲时的脉冲建立时间及相应的输出能量大小。再生放大器的增益为２×１０７。
The single pass gain of the chirped pulse in Ti∶sapphire regenerative amplifier changes with radius of the pumping beam or radius of the signal beam. With different pumping energy of frequence doubled Q switched Nd∶YAG laser, we measured the building up time and output energy when the regenerative amplifier is seeded or not seeded. The energy gain of 2×10 7 is obtained.
