Abstract

The wavefront aberration induced by turbulent flow field in liquid-convection-cooled disk laser is numerically analyzed. By using the large-eddy-simulation model, the structure of time-random turbulent eddies are described and the effects of turbulent eddies on wavefront aberration are illustrated, indicating that the wavefront aberration varies primarily with the temperature field. By integrating the thermal-induced variations of the refractive index along the laser beam path within the flowing liquid, the two-dimensional wavefront aberration is obtained, showing that the wavefront aberration occurs mainly at the thermal boundary layer, where the temperature gradient is large.
