Phase-merging Enhanced Harmonic Generation Free-electron Laser
Chao Feng, Haixiao Deng, Dong Wang +1
Together with one of its variants, the recently proposed phase-merging enhanced harmonic generation (PEHG) free-electron lasers (FELs) have been systematically studied in this pape…
Fast Polarization Switching Demonstration Using Crossed-Planar Undulator in a Seeded Free Electron Laser
Haixiao Deng, Tong Zhang, Lie Feng +13
Fast polarization switching of light sources is required over a wide spectral range to investigate the symmetry of matter. In this Letter, we report the first experimental demonstr…
Feasibility study on optical vortex generation at Shanghai deep ultraviolet free-electron laser
Haixiao Deng
Coherent light with orbital angular momentum (OAM) is of great interest, and more recently, OAM light generation by coupling a relativistic electron beam with a Gaussian mode laser…
Proposal for High-harmonic EEHG Lasing at Shanghai Deep Ultra-Violet Free-electron Laser
Tong Zhang, Chao Feng, Haixiao Deng +2
The echo-enabled harmonic generation (EEHG) free-electron laser (FEL) has been already demonstrated at lower harmonics and the first lasing at third harmonic also has been achieved…
Using Off-Resonance Laser Modulation for Beam Energy Spread Cooling in Generation of Short-Wavelength Radiation
Haixiao Deng
Various seeding configurations have being proposed for frequency up-conversion of the electron beam density distribution, in which the energy spread, may however hinder the harmoni…
Generating polarization controllable FELs at Dalian coherent light source
T. Zhang, H. X. Deng, D. Wang +5
The property of the FEL polarization is of great importance to the user community. FEL pulses with ultra-high intensity and flexible polarization control ability will absolutely op…
