The influence of wave-front-distorted pump pulse on the beam quality of the amplified signal pulse in the non-collinear optical parametric amplification(OPA) is numerically simulated.
Recognition of aquifer with both unite pump experiment data and long-time observation hole data in numerical model parametric recognition process gets a good effect.
