Abstract
"In this study, we experimentally investigate the variation of the phase matching condition of the high harmonic generation (HHG) process with pure argon gas and an argon-neon gas mixture. Phase-matched HHG is generated around the absorption edge of argon gas and then neon gas is added to the original argon gas. The pressure-dependent intensity of the harmonics produced by pure argon gas and the gas mixture is examined. We show that as more neon gas is added to the mixture, the phase matching of the higher order harmonics is less favourable than that of the lower order harmonics. Finally, the total phase mismatch at various gas mixture pressures is discussed. Our experimental results are in agreement with the theoretical calculation."
期刊介绍：
Romanian Journal of Physics was first published in 1992 as a continuation of the former Revue Roumaine de Physique (ISSN: 0035-4090), a journal publishing physics and engineering scientific papers established 1956 with deep roots in the early history of the modern Romanian physics.
Romanian Journal of Physics is a journal of the Romanian Academy published by Editura Academiei Romane (eA). The journal has an international character intended for the publication of original physics contributions from various sub-fields including the following:
-Theoretical Physics & Applied Mathematics
-Nuclear Physics
-Solid State Physics & Materials Science
-Statistical Physics & Quantum Mechanics
-Optics
-Spectroscopy
-Plasma & Laser Physics
-(High Energy) Elementary Particles Physics
-Atomic and Molecular Physics
-Astrophysics
-Atmosphere (Environmental) & Earth Science
-Environmental Protection
