Abstract :
This paper presents the fabrication of waveguides in lithium-tantalate using a 250-kHz repetition-rate ultrafast laser. Micro-Raman and second-harmonic microscopy studies indicate the preservation of optical nonlinearity in guiding regions formed by the laser-induced lattice compression.
