Ultraviolet X-Ray Laser Source for Core Level Spectroscopy and Dynamics of Metal Cluster/Ceramic Chemistry

摘要

A titanium sapphire ultrafast laser system was procured and merged with a high repetition rate pulsed valve to produce higher harmonic light output in a rare gas jet. The ultrafast laser system consists of a seed laser, a regenerative amplifier, and a two-pass power amplifier. The system operates' at 2.8 mJ energy per pulse, 75 fs pulse duration, and 1000 Hz repetition rate. Higher harmonics up to 20 eV have been observed at the 1000 Hz repetition rate by focusing the output of the laser into an argon jet. The energy of the higher harmonics is sufficient to produce excellent signals when ionizing NO.
