Abstract

We have increased the heat stability of periodically domain inverted by process improving for one-direction heating. Periodically domain inverted can be suffered from the heat treatment at 500 degrees Celsius, when the heating treatment at 500 degrees Celsius, the domain depth decreasing from initial linear becomes nonlinear compared with initial experiment results. The phenomenon of periodically inverted spikelike domains on LiTaO₃ surface disappeared, and it means that this periodically domain inverted can be used to waveguide device. The efficient intracavity second harmonic generation (SHG) was investigated using the bulk material of periodically domain inverted LiTaO₃ crystal, and 1 mW of green light at 532 nm is obtained.
