Abstract

We present what is to our knowledge the first experimental study of light-induced reflectivity changes at an α-Ga/Si interface irradiated by femtosecond and picosecond laser pulses. After exposure, the reflectivity can increase from R≊0.55 , which is typical for α-Ga , to R≊0.8 , which is close to that of liquid Ga. The initial step in the reflectivity change of 2–4 ps is resolved with 150-fs laser pulses. The light-induced reflectivity change relaxes during 100ns–10 μs , depending strongly on the background temperature of the Ga mirror and the laser fluence.
