Abstract

The invention relates to an electro-optical modulation device used for laser energy modulation in the laser pulse shot blasting technology, and is of a multi-layer film structure on the surface of a prism. The electro-optical modulation device used for the laser energy modulation in the laser pulse shot blasting technology comprises a first metal film, an electro-optical polymer film, a second metal film and a buffer layer, wherein the refractive index of the prism is higher than those of the first metal film, the second metal film, the buffer layer and the electro-optical polymer film. According to the electro-optical modulation device used for the laser energy modulation in the laser pulse shot blasting technology, which is disclosed by the invention, the Pockels effect and the Kerr effect of the conjugated polymer material are simultaneously utilized. Under the condition that the modulation voltage is not changed, direct-current bias voltage is introduced to increase the modulation degree of the device. The electro-optical modulation device used for the laser energy modulation in the laser pulse shot blasting technology is especially suitable for the laser pulse shot blasting reinforcement and formation technology, and the fine regulation of laser light spot energy is realized by regulating the direct-current operating bias voltage of a modulator.

Description

technical field [0001] The invention relates to a conjugated polymer waveguide optical modulator, in particular to an electro-optic modulator which utilizes both the Pockels effect and the Kerr effect of the conjugated polymer material. Background technique [0002] In the laser pulse peening strengthening and forming technology, the impact of the laser energy on the experimental results is the most significant. Therefore, the fine adjustment of the laser energy is a more accurate way to carry out experimental research and industrial production of laser pulse peening strengthening and forming. necessary condition. [0003] Organic polymer nonlinear (NLO) materials have attracted much attention because of their fast response time and large second-order and third-order nonlinear susceptibility. It has advantages in synthesis and processing that other NLO materials cannot match, and its structure is easy to tailor. At the same time, it has good mechanical properties and high l...
