论文摘要
具有可调波长和非常短的持续时间的深紫外线（DUV）激光脉冲是下一代技术和超快科学的关键技术。他们的一代是广泛的实验努力的主题，但是到目前为止，尚未证明任何技术能够满足一个光源中的所有要求。在这里，我们证明了基于空心毛细血管纤维中谐振的色散波发射的明亮，高效且紧凑的深紫外线超快激光脉冲。在包括基于Ytterbium的驱动激光器在内的总足迹仅为120 x 75厘米，我们以50 kHz的重复速率以208 nm至363 nm的速度产生脉冲，总效率高达3.6％。 DUV生成的缩放可以充分降低所需的能量，从而能够产生两彩几秒钟的DUV脉冲。
Deep ultraviolet (DUV) laser pulses with tuneable wavelength and very short duration are a key enabling technology for next-generation technology and ultrafast science. Their generation has been the subject of extensive experimental effort, but no technique demonstrated thus far has been able to meet all requirements in one light source. Here we demonstrate a bright, efficient, and compact source of tuneable deep ultraviolet ultrafast laser pulses based on resonant dispersive wave emission in hollow capillary fibre. In a total footprint of only 120 x 75 cm, including the ytterbium-based drive laser, we generate pulses between 208 nm and 363 nm at 50 kHz repetition rate with a total efficiency of up to 3.6%. Down-scaling of the DUV generation reduces the required energy sufficiently to enable the generation of two-colour few-femtosecond DUV pulses.
