ABSTRACT
Pulses at 1.064 μm were amplified up to 102 times by nonlinear mixing with a coherent pump wave in GaAs. The observed amplification shows a strong dependence on the intersection angle and time delay between pump and probe pulses. The effect is discussed in terms of self-diffraction by a laser-induced free-carrier grating.

    The thermocapillary effect is used to explain the phenomenon of shrinkage observed during the annealing of YBa[sub 2]Cu[sub 3]O[sub 7-δ] components. The proposed model can be used to estimate the characteristic time taken for pores to reach the surface of ceramic samples.
