Coherence and bandwidth measurements of harmonics generated from solid surfaces irradiated by intense picosecond laser pulses

Abstract:
We present measurements of the transverse and longitudinal coherence lengths of the fourth harmonic of a 1053-nm, 2.5-ps laser generated during high-intensity (up to 1019 W cm-2) interactions with a solid target. Coherence lengths were measured by use of a Young's double-slit interferometer. The effective source size, as defined by the Van Cittert-Zernicke theorem, was found to be 10-12 μm, and the coherence time was observed to be in the range 0.02-0.4 ps.
