    Power enhancement via an ion-channel in a Raman free-electron laser

    Huang, Xiaoli ; Zhang, Shi-Chang

    In: Laser Physics, 2018, vol. 28, no. 9, p. 095002

    As a high-power and high-efficiency coherent radiation source, the free-electron laser extends to two unique spectra: the region in the ultra-violet, x- and -rays, and the range in the millimeter- and terahertz-waves. Based on credible simulations, it is shown that the nonlinear power of a Raman free-electron laser in a millimeter wave range goes up and gets an increase of at least 9% when an...
