The outputs of two cw diode lasers are coupled into a flash-lamp-pumped Ti:sapphire laser cavity for regenerative amplification. Slices of each seed beam are simultaneously trapped in the cavity and amplified for approximately 33 round trips. The output is a 4.7-ns pulse, the total pulse energy is 110 mJ, and linewidths are only 50% greater than the Fourier-transform limit. The timing jitter between the pulses at the two wavelengths is less than +/-75 ps , and their relative energy is controlled by adjustment of the seed power of the cw diode lasers. Gain competition between the two frequencies does not lead to instabilities.
两个连续波二极管激光器的输出被耦合到一个闪光灯泵浦的钛宝石激光腔中进行再生放大。每个种子光束的切片同时被捕获在腔内并放大约33个往返行程。输出为一个4.7纳秒的脉冲,总脉冲能量为110毫焦,线宽仅比傅里叶变换极限大50%。两个波长脉冲之间的定时抖动小于±75皮秒,并且它们的相对能量通过调整连续波二极管激光器的种子功率来控制。两个频率之间的增益竞争不会导致不稳定性。
