“…In practice, the statistical description neglects important features of the shaped beams such as rippled substructure and temporal or spectral effects. For a confined analysis of the beam quality, the space-bandwidth-product could also be involved, which is known from signal theory [53].…”

Combining the specific advantages of high-resolution liquid-crystal-on-silicon spatial light modulators (LCoS-SLMs) and reflective or refractive micro-electro-mechanical systems (MEMS) presents new prospects for the generation of structured light fields. In particular, adaptive self-apodization schemes can significantly reduce diffraction by low-loss spatial filtering. The concept enables one to realize low-dispersion shaping of nondiffracting femtosecond wavepackets and to temporally switch, modulate or deflect spatially structured beams. Adaptive diffraction management by structured illumination is demonstrated for piezo-based and thermally actuated axicons, spiral phase plates (SPPs) and Fresnel bi-mirrors. Improved non-collinear autocorrelation with angular-tunable Fresnel-bi-mirrors via self-apodized illumination and phase contrast of an SLM is proposed. An extension of the recently introduced nondiffractive Talbot effect to a tunable configuration by combining an SLM and a fluid lens is reported. Experimental results for hexagonal as well as orthogonal array beams are presented.

“…When a laser beam is irradiated on a deformed optical surface, the propagation direction of the laser beam deviates from the theoretical direction. This leads to problems such as optical path difference and thermal lensing effects [3,4], which degrade the optical performance.…”

To study the deformation of an optical surface and its effect on optical performance, a method based on the finite element method for calculating the area of a particular deformation region of an optical surface is proposed, and a concept of effective area ratio is further introduced to describe the effect of deformation on optical performance. The principle of the method is presented, and the deformation of a potassium dihydrogen phosphate (KH2PO4, KDP) crystal is studied using this method, while the calculation accuracy is discussed. The results demonstrate that the method and the concept of effective area ratio are available for studying the deformation of an optical surface and its effect on optical performance.
