▼Description
BL1U is dedicated for developments and applications of various novel photon sources including free electron laser in the range from visible to deep UV, coherent harmonic generation in the deep UV and VUV, laser Compton scattering gamma-rays and undulator radiation with various polarization properties including optical vortex beam and optical vector beam.
The beam-line is equipped with a dedicated twin polarization variable undulator system with a buncher section, which can be used for a FEL oscillator and a VUV CHG. It is also equipped with a femto-second laser system synchronized with the accelerator, which is used for CHG, slicing, LCS and coherent THz radiation generation.
