Abstract

We report what is to our knowledge the first observation of Ince–Gaussian modes directly generated in a stable resonator. By slightly breaking the symmetry of the cavity of a diode-pumped Nd:YVO4 laser and its pump beam configuration we were able to generate single high-order Ince–Gaussian modes of high quality. The observed transverse modes have an inherent elliptic structure and exhibit remarkable agreement with theoretical predictions.

(a) Beam intensity patterns of even IGMs, IGp,mer,, measured with the CCD camera and (b) their theoretical predictions. Mode numbers p and m are shown in (a), and ellipticity in (b). The shape of IG1,1er, is independent of . When needed, some theoretical patterns were rotated to facilitate comparison with the measured patterns. The experimental setups are as follows: (#) Ro=30 cm, L=29.5 cm, without a cross hair; (&) equal but with a cross hair; (%) Ro=30 cm, L=10 cm, without a cross hair; (@) Ro=7.5 cm, L=6.8 cm, without a cross hair.
