Notizen:
Nonlinear optical excitation of crystalline quartz with intense femtosecond UV pulses yields the 2.8 eV recombination luminescence of the self-trapped exciton. The relation between the excitation and emission intensities reveals two- and three-photon kinetics for photon energies of 4.4 and 4.0 eV at excitation densities below 1018 cm−3. These power laws are not sizably influenced by transient linear absorption, self-focusing, and filamentation.
