Abstract
The optical parametric chirped pulse amplification (OPCPA) near the 800 nm wavelength has gained significant popularity in the recent years. This can be attributed to the development of laboratory-scale Ndglass lasers with their associated second harmonic generation (SHG), the mature nonlinear crystal growth technology, and the commercialized mode-locked Tisapphire oscillator. In this study, the characteristics of the 808-nm centered broad bandwidth signal OPCPA based on potassium dideuterium phosphate (DKDP) crystals are investigated. The phase mismatch in DKDP crystals for different deuteration levels of 0~99% is studied and a numerical simulation of the high energy optical parameric amplification (OPA) process with the considerations of absorption and several high deuteration levels is presented. Results show that the broadband bandwidth OPCPA at 808 nm can be obtained when the deuteration level is more than 90%.
