| 1 | High-Flux 1ookHz Attosecond Pulse Source Driven by a High-Average Power Annular Laser Beam显示文摘High-repetition rate attosecond pulse sources are indispensable tools for time-resolved studies of electron dynamics,such as coincidence spectroscopy and experiments with high demands on statistics or signal-to-noise ratio,especilly in the case of solid and big molecule samples in chemistry and biology.Although with the high-repetition rate lasers,such attosecond pulses in a pump-probe configuration are possible to achieve,until now,only a few such light sources have been demonstrated.Here,by shaping the driving laser to an annular beam,a 100 kHz attosecond pulse train(APT)is reported with the highest energy so far(51 pl/shot)on target(269 pJat generation)among the high-repetition rate systems(>10 kHz)in which the attosecond pulses were temporally characterized.The on-target pulse energy is maximized by reducing the losses from the reflections and filtering of the high harmonics,and an unprecedented 19%transmission rate from the generation point to the target position is achieved.At the same time,the probe beam is also annular and low loss of this beam is reached by using another holey mirror to combine with the APT.The advantages of using an annular beam to generate attosecond pulses with a high-average power laser are demonstrated experimentally and theoretically,The effect of nonlinear propagation in the generation medium on the annular-beam generation concept is also analyzed in detail. | Peng Ye Lenard Gulyas Oldal Tamas Csizmadia Zoltan Filus Timea Grosz Peter Jojart Imre Seres Zsolt Bengery Barnabas Gilicze Subhendu Kahaly Katalin Varju Balazs Major | 2022 | Ultrafast Science2022，，1： | 0 |
