Asymmetric high energy dual optical parametric amplifier for parametric processes and waveform synthesis

We report on an asymmetric high energy dual optical parametric amplifier (OPA) which is capable of having either the idlers, signals, or depleted pumps, relatively phase locked at commensurate incommensurate wavelengths. Idlers and signals can be order 200 mrad rms better, corresponding to a 212 as jitter λ =2 µ m. The arm OPA outputs combined 3.5 mJ signal idler, while low 1.5 mJ, with entire system being pumped 1 kHz, 18 Ti:Sapphire laser. Both arms are independently tunable from 1080 nm-2600 nm. combination relative locking, output power peak intensity, large tunability makes our ideal tool for use in difference frequency generation (DFG) strong pump regime, field waveform synthesis near-infrared. To demonstrate this ability we generate terahertz radiation through two color air plasma show influence generated intensity. lock multiple wavelengths energies opens door multitude possibilities DFG synthesis.
