Abstract
We present measurements of the coherence of EUV light generated using the process of high-harmonic upconversion of light from a femtosecond laser1. We show that, by using a phase-matched hollow-fiber geometry, the EUV light generated exhibits the highest inherent spatial coherence of any source in this region of the spectrum to date. This source generates approximately 1012 photons/sec in a fraction of an eV FWHM bandwidth around 31eV. Since this source exhibits full spatial coherence at very short wavelength, this light source represents the smallest inherent effective source-size of any light source yet created.
