A mode-locked thin-disk laser based on Yb:CALGO is demonstrated for the first time. At an average output power of 28 W we obtained pulses with a duration of 300 fs and a pulse energy of 1.3 μJ. 197 fs pulses with 0.9 μJ of energy were achieved at an average output power of 20 W. The shortest pulse duration measured in our experiments was 135 fs with a spectrum centered at 1043 nm. The experiments also revealed a very broad tunability from 1032 to 1046 nm with sub-200 fs pulses.
我们首次展示了基于 Yb:CALGO 的锁模薄片激光器。在平均输出功率为 28 W 的情况下，我们获得了持续时间为 300 fs、脉冲能量为 1.3 μJ 的脉冲。在平均输出功率为 20 W 的情况下，获得了持续时间为 197 fs、脉冲能量为 0.9 μJ 的脉冲。我们在实验中测量到的最短脉冲持续时间为 135 fs，光谱中心位于 1043 nm。实验还显示了非常宽的调谐范围，从 1032 到 1046 nm，具有亚 200 fs 的脉冲。
