Spatial filtering of high order harmonics by an OFI plasma amplifier

Original language description

It is now possible to produce a 10 Hz soft x-ray laser beam having very high optical qualities. The solution consists in seeding an optical-field-ionized population inverted plasma amplifier with the 25th harmonic of an infrared laser. This concept was successfully realized in LOA in 2004 and an extensive investigation of the source has been recently performed. Indeed we demonstrate the first diffraction-limited laser beam in the soft x-ray spectral range. This laser beam at a central wavelength of 32.8nm, emitted with a divergence of 0.67 mrad at a repetition rate of 10 Hz. The beam exhibits a regular Gaussian spatial profile, and wavefront distortions smaller than ?/17. A theoretical analysis of these results shows that this high beam quality is dueto spatial filtering of the seed beam by the plasma amplifier aperture.
