We present a self-consistent model computing the conduction band electron concentration, the electron and lattice temperatures of GaAs film on substrate during the action of femtosecond laser pulse. Upon illumination with a high-power tightly focused laser pulse the transient modulation of GaAs properties can produce a “transient metallic nanoparticle”.
