| contents | Third harmonic conversion efficiency from laser-dense plasma interactions R. Ondarza Física, Astronomía y Matemáticas Laser plasma interaction high harmonic generation A perturbative nonlinear procedure is used to account for the conversion efficiency of the third harmonic reflected from a dense plasmailluminated by a short laser pulse. It is found that the power ratio of the third harmonic to that of the fundamental is given by P3=P0 »a40 (!0=!p)2, where a0 is the amplitude of the incident wave, and !0 and !p are the optical and plasma frequency, respectively. Thispower ratio was found to be in agreement with particle-in-cell (PIC) simulations. Furthermore, the model presented here predicts a resonantenhancement around a density four times critical. This effect is captured as well by numerical simulations, and proved to be a distinctivefeature in the radiation spectra. 2005 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57064011 https://www.redalyc.org/journal/570/57064011/ https://www.redalyc.org/journal/570/57064011/html/ https://www.redalyc.org/journal/570/57064011/57064011.epub https://www.redalyc.org/journal/570/57064011/movil en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
