【Abstract】 The project of the fabrication of periodically poling KTiOPO4(PPKTP) in electric field poling and real-time monitoring methods is analysed. A new type general signal generator was introduced for the experiments, the generator possessed many advantages such as arbitrarily design of waveform and intuitional operation. On the computer, a user interface was supplied for the design of the waveform. Passing an amplification system, the output could offer modifiable high voltage power supply for the PPKTP experiments,such as high voltage square pulses and triangle pulses. By using this generator, the expectant effects had been obtained in the fabrication of PPKTP, especially in the method of real-time monitor.更多还原
