Paper Abstract

Potassium dihydrogen phosphate (KDP) is the irreplaceable nonlinear single crystal as optical frequency conversion and electro-optical switch in inertial confinement fusion (ICF) laser system. Based on the water solubility characteristics of KDP crystal, we propose an abrasive-free jet polishing (AFJP) method for KDP crystal with the purpose of improving surface quality without the embedding of particles. According to the AFJP experimental results, the jet spot generated by AFJP is of an approximately Gaussian shape. The feasibility of this approach has been studied through spot experiments. And the material removal mechanisms can be divided into contact removal and slipping removal.
