从一个时间补偿单色器的输出光子数增加到7。利用相位匹配技术，将Ti：蓝宝石激光脉冲（30 fs, 1.0 mJ, 800 nm，重复频率1 kHz）聚焦到充满氪气的1 cm长，500 μm孔径的中空光纤中。谐波光子能量在23 ~ 39 eV之间可调。目标上的输出光子数可与同一波长区域的小同步辐射相媲美。
The output photon number from a time-compensated monochromator was increased up to 7. 1 ×109photons/sec by employing phase-matching technique: Ti:sapphire laser pulses (30 fs, 1.0 mJ, 800 nm pulse at a 1 kHz repetition rate) were focused into a 1-cm-long, 500-μm-bore-diameter, hollow fiber filled with krypton gas. The harmonic photon energy was tunable between 23 and 39 eV. The output photon number on target was comparable to a small synchrotron radiation at the same wavelength region.
