摘要
A single conical growth method for long-seed crystals of KDP-based crystals, the growth method provided by the present invention, in which the lower end of the long-seed crystal is restricted by the lower tray, the upper end grows freely in a conical shape, and at the same time. The four column planes in the two directions [100] and [010] can grow, there is no problem of growth stress in the crystal growth process, and all the cut optical elements have very high optical quality. The growth process is the simultaneous growth of four columnar surfaces with very similar growth environments and is agitated by a blade-like stirring paddle in the crystal growth process, so that all cut optics have very high optical uniformity. Be prepared. Due to the unique cutting angle of the triple-multiplying element of the KDP-based crystal, the cutting efficiency when cutting the triple-multiplying element using the crystal grown in the present invention is very high, and the size of the horizontal dimension of the grown crystal is large. The area of the maximum triple-multiplying element that can be cut can also be known in advance. [Selection diagram] Fig. 2
