【摘要】 在实验研究的基础上提出了一套完整地用于测量被动锁模钛宝石激光器时序紊乱度的方案 ,即 :对于具有较小的时序紊乱度的激光器系统 ,频域法是主要的测量方法 ;对时序紊乱度较大的激光器系统的测量 ,频域法不再适合 ,而使用同步扫描相机的时域法具有更加精确的优点。采用腔长调变的方法对被动锁模钛宝石激光器的时序紊乱度进行了控制 ,使时序紊乱度由 6 .6 0ps降低到 0 .47ps。更多还原

【Abstract】 The methods for completely measuring the timing jitter of passively mode locked Ti∶sapphire laser are proposed. It is demonstrated that for the laser system with smaller timing jitter, frequency domain measurement is the major method, whereas for the system with larger timing jitter, frequency domain measurement is not suitable. Instead of that the method of using synchroscan streak camera is more precise. With the technique of actively cavity length controlling, the timing jitter of passively mode locked Ti∶sapphire laser has been reduced from \{6.6 ps\} (before controlling) to \{0.47 ps.\}更多还原
