“…Ince-Gaussian beam is propagated in thermal lens medium and it is concluded as received eld is written using beam width and curvature [12]. Another study states [13] that thermal effects changes pro le of Ince-Gaussian beam. While Ince-Gaussian beam propagates in uniaxial crystal orthogonal to optical axis, beam gets longer along optical axis [14].…”

Scintillation behavior of Ince-Gaussian(IG) beam is studied in this paper. Split step propagation model is applied to find scintillation index. Our results reveal that beam order and degree have strong effect on scintillation under strong turbulent conditions. In addition to these parameters, ellipticity plays a vital role on scintillation characteristics especially in weak turbulent regime. Significant amount of degradation in scintillation attracts the attention. Among IG beam settings, scintillation index of even modes is less comparing with odd modes. Therefore, it is anticipated that performance of optical wireless communication systems increases when IG beam is used.

“…Despite the impressive body of work, most studies have restricted their analysis to the common example of creating and delivering a high-power Gaussian beam with some studies on the thermal effects of Bessel-Gaussian beams [37], Ince-Gaussian beams [38,39] and Helmholtz-Gaussian beams [40] being available. It has also been demonstrated that annular pump beams could be used to reduce the thermal lensing effect on Gaussian beams passing through the centres of gain media [41,42] although the overlap with the Gaussian mode is poor.…”

Structured light, where optical beams are tailored in amplitude, phase and polarisation to some desired profile, has become topical of late, fuelled by the ease at which such fields can be created internal and external to the source. In this treatise, part I of a two part series, we consider the thermal effects (stress, lensing and phase aberrations) associated with high-power structured light, where the structure may be the pump, optically inducing the thermal effects in the medium, or the probe, experiencing thermally induced optical aberrations. We outline a general theory for arbitrary structured light pumps and probes, reducing to the prior studies of Gaussian and flat-top beams as special cases. We illustrate the power of the model using the structure of light as a new degree of freedom with which to mitigate thermally induced optical aberrations. Finally, in part II of this composite work (Scholes and Forbes, Appl Phys B, 2021.

“…However, high power laser studies involving the impact of thermal aberrations on structured light fields and the mitigation thereof remain largely neglected due to the complexity of the experiments. The limited studies include thermal and gain effects on Ince-Gaussian beams [25,26], Helmholtz-Gaussian beams [27] and Bessel-Gaussian beams [28], as well as some intra-cavity mode control with adaptive optics [29][30][31][32][33][34]. It has also been demonstrated that annular pump beams could be used to reduce the thermal lensing effect on Gaussian beams passing through the centre of the optic [35,36].…”
