Harmonic-enhanced high-gain harmonic generation for a high repetition rate free-electron laser
文献摘要:
High-gain harmonic generation(HGHG)is effective to produce fully coherent free-electron laser(FEL)pulses for various scientific applications.Due to the limitation of seed lasers,HGHG typically operates at a low repetition rate.In this paper,a harmonic-enhanced HGHG scheme is proposed to relax the peak power requirement for the seed laser,which can therefore operate at megahertz and a higher repetition rate.Moreover,the setup of the scheme is compact and can be adopted in an existing single-stage HGHG facility to extend the shortest achievable wavelength.Simulations show that FEL emission at 13.5 nm(20th harmonic)can be obtained with a 270 nm,1 MW(peak power)seed laser.
