The invention provides an optical element preparation method and a laser drying treatment system and relates to the technical field of laser. The optical element preparation method comprises the stepsthat sol-gel is prepared; a fused quartz substrate is provided, and an optical film layer is made and formed on one surface of the fused quartz substrate through the sol-gel; drying treatment is conducted on the optical film layer through laser to obtain a fused quartz optical element including the fused quartz substrate and the optical film layer. By adopting the method, the light transmittanceof an existing fused quartz optical element can be further improved. 本发明提供的光学元件制备方法和激光干燥处理系统，涉及激光技术领域。其中，所述光学元件制备方法包括：制备溶胶-凝胶；提供熔石英基底，并通过所述溶胶-凝胶在所述熔石英基底的表面制作形成光学膜层；通过激光对所述光学膜层进行干燥处理，以得到包括熔石英基底和光学膜层的熔石英光学元件。通过上述方法，可以进步提升现有的熔石英光学元件的透光率。
