The experimental intensities have been compared with the standard second-order theory of two-photon processes for both intermultiplet and intramultiplet transitions between individual crystal-field levels. Adequate agreement is found in the case of ErPO&lt;sub&gt;4&lt;/sub&gt;, but serious discrepancies exist for TmPO&lt;sub&gt;4&lt;/sub&gt;. It is shown that electronic Raman scattering is a sensitive technique for testing the Judd-Ofelt–type theories of two-photon processes in rare-earth crystals. Strong asymmetry, a characteristic feature of electronic Raman scattering, has been observed in several of the transitions.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">12</style></issue><notes><style face="normal" font="default" size="100%">&lt;p&gt;NOT IN FILE&lt;/p&gt;</style></notes><section><style face="normal" font="default" size="100%">8102</style></section><label><style face="normal" font="default" size="100%">Laser</style></label></record></records></xml>
