Abstract

The invention relates to a novel optical parametric chirped pulse amplification method which overlays and enhances original pump light in a cavity by making use of the structure of a ring cavity so as to enhance the power density of the pump light and then reuses the pump light by making use of optical path difference of signal light and the pump light in respective cavities thereof so as to improve transformation efficiency. At last, the method adopts a cavity dumping technique, chooses optimal parametric amplification times and controls the saturation effect during the parametric process to overlay and enhance the original pump light in the cavity. The method makes use of the structure of the ring cavity to ensure the pulse front edge and back edge of the pump light are overlaid in the cavity and has the advantages of making use of pumping source with wide pulse and high energy to obtain high energy burst pulse output and improving the transformation efficiency of the pump light to the utmost extent.

Description

technical field [0001] The invention relates to a novel optical parametric chirped pulse amplification method, which belongs to the ultrafast laser pulse amplification technology. The method combines the characteristics of multi-pass parametric amplification and intracavity superposition enhancement, and can realize the full utilization of pumping light energy, thereby Optimize conversion efficiency. Background technique [0002] High peak power and high single pulse energy are important means to study the interaction of matter under extreme physical conditions, so how to obtain ultrashort and intense laser pulses has become one of the hot research fields at home and abroad. At present, there are three main methods of optical pulse amplification: one is the chirped pulse (CPA) amplification method, which is to broaden the femtosecond seed optical pulse in the time domain, then amplify it through a laser gain medium, and finally use a compressor to compress the pulse width to...
