A 400 fs high-repetition rate fiber laser system (Amplitude, Tangerine) was newly installed. The fiber laser system, which is operated at 1030 nm fundamental wavelength, is capable of reaching up to 0.1 mJ pulse with a repetition rate of 400 kHz. A higher harmonic generation system enlarges the spectral range from UV to mid-infrared. To increase the laser power density at a sample position, the x-ray was additionally focused by a polycapillary lens (Polycapillary Optics, XOS). The synchronization of X-ray and laser pulses is based on the RF master clock of the storage ring. The delay between the laser and the X-ray is controlled by changing the emission timing of the laser with a Trigger & Clock Delay Module (84DgR5CO1, CANDOX). The high repetition rate system increases experimental efficiency 400 times.
