Paper Abstract

This paper reports the innovative structure and working properties of a high-power window cooled with solid-liquid phase change. When the power density of output laser beam is 2.5kw/cm2 and the lasting time is 4seconds, the largest thermal deformation of this window is about 0.45um, approximately equal to 1/4 that of normal quartz window, under the same conditions. And the far field divergence angle of the laser beam from the window has been reduced by 1.2 diffraction limits, by contrast to the one from the normal quartz window.
