Abstract: The existence of temperature-noncritical phase matching in second-harmonic generation was discovered for the first time theoretically and confirmed experimentally. A temperature phase-matching bandwidth in excess of 200°C was found experimentally for a potassium titanyl phosphate (KTP) crystal of 7.7 mm length at the fundamental-radiation wavelength 1064.2 nm.
