Abstract

Laser heating of glass samples is a simple and versatile method for obtaining polished surfaces of optical quality. Since laser beam intensity non-uniformity can translate into significant variations in the induced surface temperature, the success of the laser surface-polishing process strongly depends on obtaining uniform intensity profiles or flat-top distributions at the sample plane. In this paper we present a comparison between large-area CO₂ laser-polishing experiments carried out in optical glass substrates following two different approaches: (1) A reshaped beam obtained by an active integration method is swept over the glass surface. (2) A static beam reshaped by means of both a multifaceted mirror and a square pipe light guide is applied.
