Abstract
An efficient but simple scheme of an axicon-based resonator for tuning the spatial mode of high-power and high-order Bessel–Gaussian beams is proposed. This scheme is extended for two types of high-power lasers: continuous wave (CW) and Q-switched lasers. More importantly, the right axicon apex angle, the resonator optical length and the internal aperture diameter and its place inside the resonator are theoretically deduced for adjusting the transverse mode order of the laser. Furthermore, high-power Bessel–Gaussian beams with both active and passive arrangements are set up. The experimental results verify the validity of the theoretical model and the accuracy of the selected parameters. In this paper, an effective guideline is presented for designing more efficient, more compact, and easier-to-fabricate sources of high-power and high-order Bessel–Gaussian beams with transverse mode tuning.
