DOI: 10.1088/0256-307x/36/11/114201
Abstract: We demonstrate laser ultrasonic generation in polyetheretherketone (PEEK). A middle infrared ZnGeP2 optical parametric oscillator (ZGP-OPO) pumped by a Q-switched Ho:YAG laser is employed as the ultrasonic excitation source. The ZGP-OPO has a spectral range… read more here.
