Paper Abstract

The new method of surface shaping for optical plastics have been investigated using UV laser ablation on acrylic resin (PMMA) or ultraviolet (UV)-cured-resin. The surface figuring of optical flat was obtained with direct beam irradiated ablation with ArF laser. The depth of the figuring was determined with the measurement of wave front distortion on the optics using interferogram. The ablated surface had small surface roughness. The miniature size optics such as the collimate lens for a diode laser (LD) was fabricated on flat PMMA at using the focusing beam irradiation. The wave front of LD light through the LD lens was measured with Shach-Hartmann sensor. The wave front control for LD light was carried out with the measured wave front data by the laser ablation on the LD lens surface. The collimated LD light has been obtained.
