Abstract To optimize the intensity of X-ray free-electron lasers (XFELs), phase shifters, oriented in phase with the phases of the XFEL pulse and electron beam, are typically installed at undulator lines. Although a π-offset between the phases (i.e.

By using split-step Fourier method, we conducted the simulation of pulse formation in two SESAM mode-locked lasers. One is a conventional laser with the SESAM at the cavity end. The other is constructed by moving the SESAM of the conventional laser t

Relativistic Plasma Waves and Particle Beams as Coherent and Incoherent Radiation Sources IV.
Laser plasma wakefield accelerations (LWFA) are the most promising candidates for future compact accelerators and also can be used for next-generation free-electron lasers (FELs). However, due to the insufficient electron beam quality, such as a few

Coherent anti-Stokes Raman scattering spectroscopy suffers from spectral distortion and low signal to noise ratios due to the influence of nonresonant background. To make the spectral information useful, phase retrieval was used through the Kramers-K

To establish the operating characteristics of a saturable absorber mirror (SESAM)-assisted mode-locked laser oscillator depending on the location of the SESAM, we designed a laser oscillator with the SESAM toward the middle of the cavity. We then com
