Tvorba višjih harmonikov svetlobe

Članek predstavlja proces generiranja koherentnih pulzov močne ultravijolične svetlobe pri interakciji laserske infrardeče svetlobe s plinom. Mehanizem tvorbe višjih harmonikov svetlobe (High Harmonic Generation) je razložen s trikoračnim modelom, ki gibanje elektrona v elektromagnetnem polju laserja obravnava klasično. Opisana je tudi naprava HHG, ki jo pravkar postavljajo na Univerzi v Novi Gorici in bo služila za opazovanje hitrih procesov v snovi.

High harmonic generation

This article presents the process of generating coherent pulses of extreme ultra-violet light by interaction of a strong infra-red laser light with a gas. The mechanism of high harmonic generation is explained through a three step model, which classically describes the motion of an electron in the electromagnetic field of the laser. The article also describes the HHG installment at the University of Nova Gorica, which is going to be used for observing fast processes in matter.
