Paper Abstract

Thin disk laser is the most successful design to overcome the degradation of the beam quality caused by the gain medium's thermal effects and has many advantages in beam quality keeping and power scalability over the traditional rod and slab laser. In this paper a different type thin disk laser with the large-aperture Nd:YAG disk face-pumped by 2D-stack diode arrays was presented. Over 3kW average power with the beam quality less than 10 times diffraction limitation was achieved by optimizing the pumping optics designs and improving the gain medium mounting technique.
