In this work, we report the optical waveguide formation in LiTaO3 crystal via Ar8+ ion irradiation at an energy of 180 MeV and a fluence of 2×1012 cm−2. The surface damage behavior of LiTaO3 crystal and structure change along the ion trajectory are studied through Rutherford backscattering/channeling spectra and micro-Raman spectra, respectively. The modal profile measurement through end-face coupling...
Continuous-wave (CW) and passively Q-switched operations of laser diode-end-pumped Nd:CLTGG laser at 1.06 μm was demonstrated for the first time. The laser spectrum was found to be tri-wavelength, with respective wavelengths of 1058.4, 1060.5, and 1065.5 nm for both CW and passive Q-switching regime. The highest CW output power of 2.6 W was obtained with an optical-optical conversion efficiency of...
