Abstract
Investigations of nonlinear-optical frequency conversion of Nd:YAG laser radiation in naphthalene vapors are presented. Third harmonic generation caused by difference frequency generation in six-photon process was offered. Optimum temperature for naphthalene vapor was found to be 170 degree(s)C, at which the synchronous conversion of pump radiation to the third harmonic radiation was carried out. Third harmonic generation conversion efficiency varied within the 10-10 depending on pump intensity and cell temperature. Third-and fifth-order nonlinear-optical susceptibilities of naphthalene vapors were calculated.
