Abstract: Extremely high equivalent temperatures of optical phonons were obtained in GaAs without detectable increase in the lattice temperature. The improvement upon previous experiment was due to the use of a pulsed Nd:Yag laser which was doubled by the GaAs sample itself and absorbed in its bulk. The non-equilibrium LO-phonon population attained before crystal breakdown was ∼ 27 times larger than the thermal equilibrium population at the room temperature (290K). The equivalent temperature observed for LO-phonons was ∼3700K. © 1974.
