چکیده

Tunable coherent radiation was produced at 35.5 nm by seventh-harmonic conversion of 248-nm radiation from a krypton fluoride excimer laser. The nonlinear interaction took place at the intersection of the laser focus and a pulsed, supersonic helium gas jet. Third- and fifth-harmonic generation produced coherent outputs at 83 and 50 nm in both helium and xenon gas jets.

Coherent control of frequency conversion toward short (picosecond) vacuum-ultraviolet radiation pulses

We present experimental data on the coherent control of frequency conversion toward the vacuum-ultraviolet regime in xenon atoms, applying intense ultrashort picoseconds (ps) radiation pulses. We report on quantum interference between two resonantly enhanced frequency conversion processes (i.e., fifth harmonic generation and four-wave mixing). The conversion processes are driven by a fundamenta...

A Source of Coherent Soft X-ray Radiation Based on High-order Harmonic Generation and Free Electron Lasers∗

We examine a scheme for a Free Electron Laser (FEL) harmonic amplifier seeded by a 30-nm wavelength signal produced using a process of High-order Harmonic Generation (HHG). The seed is first amplified in an optical klystron from 100 kW to 30 MW using a 1 GeV electron beam and then is used for an energy modulation of electrons in the downstream undulator. Subsequently, a 100MW level of radiation...
