(a) Gain spectra (solid curves) and phase mismatches (dashed curves) for a 2.108 μm degenerate OPA pumped at 1.054 μm. Red, green, and blue curves correspond to LGN and LiNbO3 crystals. (b) Comparisons under the same gain for different crystals. Reprinted with permission from [21]. Copyright 2016 Optical Society of America.
