Chirp effects in femtosecond laser-induced surface second harmonic generation from metals

Open Access Open Access

Abstract

Chirp effects are studied in femtosecond laser-induced surface SHG from metals. The study shows that the SHG signals change dramatically with pulse chirp, indicating a critical dependence of nonlinear efficiency on the wavelength sequence within femtosecond pulse bandwidth when electrons contributing to SHG are heated to a high temperature.
