Abstract: Temperature-noncritical third harmonic generation is studied theoretically and experimentally in an LBO crystal by compensating for the temperature-induced deviation of the phase-matching direction due to thermal strains in the crystal. The width of the phase-matching temperature curve obtained experimentally in a 14.1-mm-long LBO crystal for the third harmonic generation of the 1.064-μm radiation is 73 °C.
