我们提出了我们认为是第一个太瓦二极管泵浦激光器采用单晶Yb：CaF（2）作为放大介质。在1 Hz的重复率下，最大脉冲能量为420 mJ，通过使用持续时间为2 ns的拉伸飞秒脉冲进行播种，预放大至40 mJ。再压缩后，获得了197 mJ的脉冲能量和192 fs的持续时间，对应于1 TW的峰值功率。此外，纳秒脉冲包含高达905毫焦耳的能量产生无光学损伤。
We present what we believe to be the first terawatt diode-pumped laser employing single-crystalline Yb:CaF(2) as the amplifying medium. A maximum pulse energy of 420 mJ at a repetition rate of 1 Hz was achieved by seeding with a stretched femtosecond pulse 2 ns in duration, preamplified to 40 mJ. After recompression, a pulse energy of 197 mJ and a duration of 192 fs were obtained, corresponding to a peak power of 1 TW. Furthermore, nanosecond pulses containing an energy of up to 905 mJ were generated without optical damage.
