摘要：
Results of experimental and theoretical investigations on generation of terahertz radiation at the interaction of femtosecond laser pulses with a metal surface are presented. Investigations are performed with the laser pulse intensities higher compared with that used in papers [Opt. Lett. 29, 2674 (2004); Opt. Lett. 30, 1402 (2005)]. The most effective generation is observed for p-polarized optical pulses with incidence angles in the range 5 degrees-10 degrees (from the surface), depending on the kind of metal. For the copper, the exponential growth of terahertz pulse energy with the increase of optical pulse energy was registered. Theoretical interpretation for some of the experimental results is proposed based on the model of free electrons in metal. (C) 2012 Optical Society of America
