Abstract
The non-collinear phase-matching of 808 nm centered optical parametric amplification(OPA) is analyzed in detail in potassium dideuterium phosphate (DKDP) crystal. Phase-matching parameters for various deuteration DKDP crystals are calculated based on the concepts. Optical parametric chirped pulse amplifier(OPCPA) based on 95% deuteration DKDP crystal is designed and the output characteristics are simulated by OPA coupled wave equations for further discuss. It is concluded that DKDP crystals higher than 90% deuteration level can be utilized in ultra-short high power laser systems with compressed pulses broader than 30 fs. The disadvantage is that the acceptance angles are small, increasing the difficulty of engineering regulation.
