Abstract

The relation of the spectral angular dispersion with the fundamental wavelength(FW) and the grating period of simultaneously quasi phase matching(QPM) and group velocity(GV) matching in tilted second harmonic generation is carried out in periodically poled RbTiOAsO₄(PPRTA).The phase matching bandwidth of PPRTA of noncollinear (2D) phase matching with spectral angular dispersion( 31.37nm, 218.41nm ) is 58 times and 15 times of those of collinear(1D) phase matching( 0.54nm,14.38nm )as the fundamental wavelength is 0.8μm and 1.55μm has been obtained, respectively.
