Abstract
Provided is an optical parametric oscillation laser based on I-type quasi-phase matching. The optical parametric oscillation laser comprises a femtosecond laser pumping source (), an input coupling mirror (), an Mg:PPLN crystal (), an output coupling mirror () and a beam splitter prism (), wherein the femtosecond laser pumping source () of a synchronous pump, the input coupling mirror (), the Mg:PPLN crystal (), the output coupling mirror () and the beam splitter prism () are sequentially placed. Group velocity mismatching between near-infrared pump light and intermediate infrared signal light in the intermediate infrared optical parametric oscillation laser is eliminated by using the dispersion relationship between the crystal and the temperature and in a manner of adjusting the working temperature of the crystal, so that an optical parametric oscillation process can satisfy phase matching and group velocity matching at the same time, and therefore intermediate infrared ultrashort pulse laser with high power and wide spectrum is obtained.
