Short wavelength regenerative amplifier free elec - tron lasers

چکیده
A regenerative amplifier free-electron laser (RAFEL) is a highgain resonator FEL which achieves saturation in a few round-trips of the radiation in a high-loss, and hence low feedback, optical cavity. Because the radiation feedback fraction is low it is feasible that the use of low reflectivity optics in the resonator makes the RAFEL a candidate for short wavelength operation [1]. Several RAFEL proposals have been made in the VUV [2,3] and X-ray [4] and some experimental results obtained [5,6].

Electron Microscopy
Electron microscopy uses high-energy elec tron beams to probe the structure and chem istry of both inorganic and biological materi als. The short wavelength (A) of electrons permits higher resolution images than light microscopes. This was a major motive in the early development of the transmission elec tron microscope (TEM) by Knoll and Ruska (1932) in Berlin, and atomic resolution is now rout...

We report a stable optical fiber pumped Nd:YVO4 all solid state regenerative amplifier with all fiber picosecond laser as seed source. 888 nm Yb optical fiber lasers was chosen as pump source to reduce quantum defect for improved thermal performance. At the repetition rate of 99.6 kHz, maximum power of 19.63 W with 36 ps pulse duration were achieved when seeded by a 150 mW picosecond oscillator...
متن کاملGeneration of ultrashort radiation pulses by injection locking a regenerative free-electron-laser amplifier
We demonstrate how a steady-state train of ultrashort radiation pulses can be produced utilizing a new free-electron laser ~FEL! configuration, the injection-locked regenerative klystron amplifier ~IRKA!. This configuration consists of two elements: ~1! a prebuncher, which microbunches the electron beams at the desired output wavelength, and ~2! a multipass FEL operated at a very small cavity d...

متن کاملRegenerative spectral and pulse shaping of high average power chirped pulse thin-rod Yb:YAG amplifier
Spectral gain narrowing of high-average power, regenerative chirped pulse thin-rod Yb:YAG amplifier was compensated by the regenerative spectral and pulse shaping technique. An average output power of 18 W was achieved at a repetition rate of 100 kHz with an output pulse width of below 1.2 ps. A wide spectral bandwidth of 2.5 nm was also observed. 2009 Optical Society of America OCIS codes: (1...
