D-shaped fibers have attracted widespread attention due to their special structure and excellent performances. However, the fabrication of D-shaped fiber faces many challenges. Mechanical polishing and chemical etching are two traditional methods for D-shaped fiber fabrication, in which micro-crack or contamination is unavoidable. In this paper, we report an efficient method to produce D-shaped fiber with a pulsed CO₂ laser. The effects of processing parameters on processing efficiency and surface quality are investigated experimentally, and the processing defects such as melting debris and oscillation are also studied. The optimized processing parameters are provided.
