Rocca, Generation of Millijoule-Level Soft-X-Ray Laser Pulses at a 4-Hz Repetition Rate in a Highly Saturated Tabletop Capillary Discharge Amplifier, Optics Letters 24, no. 16 (August 15, 1999): 1115-1117.http://hdl.handle.net/10217/67514Laser pulses with energies of as much as 1 mJ were generated at a wavelength of 46.9 nm by single-pass amplification in a 34.5 cm-long Ne-like Ar capillary discharge plasma. The large gain-length product of this plasma column allows for soft-x-ray amplification in a highly saturated regime, resulting inefficient energy extraction. Average laser output pulse energy of 0.88 mJ and peak power of 0.6 MW were obtained at a repetition rate of 4 Hz. With an estimated peak spectral brightness of ≈1 × 1023 photons/s mm2 mrad2 0.01% bandwidth) this tabletop laser is one of the brightest soft-x-ray sources to date.born digitalarticleseng©1999 Optical Society of America.Copyright and other restrictions may apply.
