A thorough theoretical analysis of the near-infrared properties of periodically poled KTiOPO4 (PPKTP) and stoichiometric MgO-doped LiTaO3 (MgO:PPSLT) crystals for optical parametric oscillation with excitation at 1 mu m is presented. To the best of our knowledge, the optical, phasematching, wavelength tuning, and dispersive properties of these crystals for parametric interactions are discussed in detail for the first time. In addition, a new design for high power parametric devices based on PPKTP or MgO:PPSLT crystals with ultrafast Yb-ion laser pump is proposed. The results form a useful reference for the selection of materials and operating conditions for the practical design of high power femtosecond optical parametric oscillators with excitation at 1 mu m.
