Experiments reveal an increment in the transmission of gallium arsenide during illumination in its transparency spectrum by an intense picosecond light pulse. The experimental results agree qualitatively with the theory derived by Kumekov and Perel' {Fiz. Tekh. Poluprovodn. 18, 835 (1984) [Sov. Phys. Semicond. 18, 520 (1984) ]}, which is based on the concept of Galitskii-Goreslavskii-Elesin quasiparticles {Zh. Eksp. Teor. Fiz. 57, 207 (1969) [Sov. Phys. JETP 30, 117 (1969)]}.
