We report on the observation of quasi-phase matched collinear second harmonic generation (SHG) at 20 wavelengths in a two-dimensional nonlinear photonic quasi-crystal with decagonal lattice. We show that at some wavelengths the second harmonics are generated via standard quasi-phase matching, namely
The angular acceptance angle (phase matching acceptance angle) Dy in BBO crystal is theoretically calculated in milli-radian magnitude. To satisfy a fully phase matching condition of a laser beam and obtain ecient conversion of SHG, an intracavity frequency doubled (IFD) Nd:YAP mode-locked laser wit
E cient intracavity second-harmonic generation (SHG) has been realized in a new Li-doped GdCa 4O(BO 3) 3 (GdCOB) crystal. 2:55 W CW SHG output power was obtained with an optical conversion e ciency of 19.6%, while the e ective intracavity SHG e ciency was determined to be 44%. Compared to that of un
