Designing of an efficient multi-aperture, edge pumped thin-disk laser

► Based on a numerical model, an edge-facet pumped asymmetric hexagonal disk laser is optimized. ► Due to special shape of crystal, this configuration allows the multiple pass of the pump beam. ► Absorbed energy efficiency, uniformity and disk temperature are triplet designing parameters. ► In compare, in this configuration, absorption efficiency and uniformity are improved. ► Results show this geometry is a high efficient configuration for thin gain lasers.
