| titleOfInvention | A kind of laser energy stability device and its energy stabilization method based on prefix pulse |
| abstract | The invention discloses a kind of laser energy stability device and its energy stabilization method based on prefix pulse, belong to laser technology field, including main optical path and sampling light path, the main optical path includes seed light source, Pockers cell electrooptical switching, slicing switch, and the sampling light path includes what is set gradually：Beam splitter, light intensity adjustable attenuator, photoconductivity switching, the two poles of the earth of the both ends of the photoconductivity switching respectively with Pockers cell electrooptical switching are connected, the present invention is combined using Pockers cell electrooptical switching with photoconductivity switching, apply voltage on Pockers cell electrooptical switching in advance, a prefix pulse is first produced before laser pulse, go to change the dynamic resistance value of photoconductivity switching using the fluctuation of energy of prefix pulse, so as to change the virtual voltage of Pockers cell electrooptical switching and the transmissivity of Pockers cell electrooptical switching, realize and the energy stabilization of laser pulse is controlled, with the feature that same hair is stable, and the time waveform of laser pulse is set not to be distorted. |
