主　　题：nonlinear optics frequency doubling multi-color laser quasi-phase matching 

摘      要：Frequency conversion based on three-wave mixing is a critical nonlinear optic application,extending the frequency range of existing lasers and realizing frequency-transduced detectors in a wavelength range that lacks an effective *** matching is vital for effective frequency *** advantages of quasi-phase matching(QPM)over birefringent phase matching are a lack of walk-off effect,a maximum nonlinear coefficient,and phase matching in the entire transparency ***,using different types and orders of QPM,four kinds of effective frequency doubling processes are realized in a periodically poled potassium titanyl phosphate(KTP)crystal with a single period,and three kinds of frequency doubling processes are experimentally *** also show a feasible way to construct an RGB color generator based on two different QPM *** study significantly expands the feasible frequency conversion of existing lasers to different wavelengths,providing an effective method for multi-color laser generation based on periodically poled KTP crystals.
