TL;DR: The random and uncontrollable spikes, which appeared in the spectra of the Self-Amplified Spontaneous Emission (SASE) based FEL radiation without the seeding source, were found to be suppressed drastically to form to a narrow-band, single peak profile at 61.2 nm.
Journal ArticleDOI
Highly Efficient Continuous-Wave Laser Oscillation in Microchip Yb:YAG Laser at Room Temperature
TL;DR: In this paper, a high-intensity Ti:sapphire laser pumping was used to achieve an output power of 810 mW at 1048 nm wavelength oscillation, which is close to the quantum-defect-limit of 90%.
Journal ArticleDOI
Time-interleaved multienergy acceleration for an x-ray free-electron laser facility

TL;DR: In this paper, the authors proposed to deliver bunch-to-bunch energy changed electron beams at the end of the accelerator, which enables quasisimultaneous operation of multi-beam-line in the same undulator hall without degrading the stability and performance of the electron beam.
Journal ArticleDOI
