Abstract

An x-ray multilayer monochromator with improved resolution and a low specular background is presented. The monochromator consists of a lamellar multilayer amplitude grating with appropriate parameters used at the zeroth diffraction order. The device is fabricated by means of combining deposition of thin films on a nanometer scale, LTV lithography, and reactive ion etching. The performance of this new monochromator at photon energies near 1500 eV is shown. OCIS codes: 340.0340, 300.6560.

Abstract

The first longitudinal coherence measurement of the transient inversion collisional xray laser is presented. The scheme under study is the picosecond output of the Ni-like Pd x-ray laser at 14.68 nm generated by the COMET laser facility at LLNL. Interference fringes were generated using a Michelson interferometer setup in which a thin multilayer membrane was used as a beam splitter. Longitudinal coherence measurements were made for this transition by changing the length of one interferometer arm and measuring the resultant variation infringe visibility. The nature of this dependence also allows for an estimation of the linewidth of the lasing transition to be made. Analysis indicates a linewidth of ∼0.3 pm which is a factor of four less than previous measurements on quasi-steady state x-ray laser schemes. [ABSTRACT FROM AUTHOR]
