主　　题：optical waveguides Nd:GdCOB crystal second harmonic generation 

摘      要：Carbon ion irradiation and precise diamond blade dicing are applied to fabricate Nd∶GdCOB ridge *** propagation properties of the fabricated Nd∶GdCOB waveguides are investigated through experiments and theoret-ical ***-Raman analysis reveals that the Nd∶GdCOB crystal lattice expands during the irradiation ***-second harmonic spectroscopic analysis suggests that the original nonlinear properties of the Nd∶GdCOB crystal are greatly enhanced within the waveguide *** pulsed 1064 nm laser pumping,second harmonic generation(SHG)at 532 nm has been achieved in the fabricated *** maximum SHG conversion efficiencies are determined to be~8.32%·W^(-1) and~22.36%·W^(-1) for planar and ridge waveguides,respectively.
