S. Varro et F. Ehlotzky, HIGHER HARMONIC-GENERATION AT METAL-SURFACES BY POWERFUL FEMTOSECOND LASER-PULSES, Physical review. A, 54(4), 1996, pp. 3245-3249
We present a simple model calculation to interpret the recent data of
Kohlweyer ct al. [Opt. Commun. 117, 431 (1995)] and von der Linde ct a
l. [Phys. Rev. A 52, R25 (1995)] on the generation of higher harmonics
at metal surfaces by powerful femtosecond laser pulses. The model pre
sents an adaptation of our earlier work [Phys. Rev. A 49, 3106 (1994)]
to the present situation.
