在深紫外区产生和表征超短激光脉冲是具有挑战性的，特别是在高重复频率和低脉冲能量的情况下。这里，我们将消色差二次谐波产生和自适应脉冲压缩相结合，有效地产生了重复频率为200 kHz的亚10ps深紫外光脉冲。此外，我们简化了脉冲压缩方案，在不使用自适应光学的情况下，脉冲持续时间可达到近10ps。我们展示了从250 nm到320 nm的直接调谐、高达63 nm宽度的宽脉冲谱、出色的稳定性和对未对准的高度稳健性。这些特点使得这种方法在许多光谱和成像应用中具有吸引力。由光学学会根据知识共享署名4.0许可证的条款出版。
The generation and characterization of ultrashort laser pulses in the deep ultraviolet spectral region is challenging, especially at high pulse repetition rates and low pulse energies. Here, we combine achromatic second harmonic generation and adaptive pulse compression for the efficient generation of sub-10 fs deep ultraviolet laser pulses at a laser repetition rate of 200 kHz. Furthermore, we simplify the pulse compression scheme and reach pulse durations of approximate to 10 fs without the use of adaptive optics. We demonstrate straight-forward tuning from 250 to 320 nm, broad pulse spectra of up to 63 nm width, excellent stability and a high robustness against misalignment. These features make the approach appealing for numerous spectroscopy and imaging applications. Published by The Optical Society under the terms of the Creative Commons Attribution 4.0 License.
