Abstract:
The present invention discloses a method for smoothing a surface of an optical element with a laser. Firstly, an optical element having a rough surface is provided. Next, the rough surface of the optical element is illuminated with a laser. The rough surface absorbs laser energy and melts into a liquid. The liquid is stretched and planarized by the surface tension of the rough surface and then solidifies into a smooth surface. The present invention can smooth the surface of an optical element and promote the resonant or waveguide performance of the optical element.
