Poling pattern for efficient frequency doubling of Gaussian beams
The commonly used periodic patterning for quasi phase-matching plane-waves is theoretically adequate for completely depleting and transferring a fundamental wave to its second harmonic. However, when working with Gaussian beams the conversion efficiency of such a design lacks due to the inherent Gouy phase shift and the spatially varying beam profile, yielding roughly 88 % conversion efficiency...
متن کاملA spatial frequency-doubling illusion-based pattern electroretinogram for glaucoma.
PURPOSE A pattern electroretinogram (PERG) in which stimuli displaying the frequency-doubling (FD) illusion are presented simultaneously to multiple parts of the visual field was evaluated for its ability to diagnose glaucoma. This multiregion FD PERG is referred to in the current study as the MFP. METHODS The nine stimulus regions were temporally modulated at incommensurate frequencies typic...
متن کاملulerian Gaussian beams for high-frequency wave propagation
We design an Eulerian Gaussian beam summation method for solving Helmholtz equations in the high-frequency regime. The traditional Gaussian beam summation method is based on Lagrangian ray tracing and local ray-centered coordinates. We propose a new Eulerian formulation of Gaussian beam theory which adopts global Cartesian coordinates, level sets, and Liouville equations, yielding uniformly dis...
متن کاملEfficient Transformation of Gaussian Beams into Uniform, Rectangular Intensity Distributions
Introduction and Overview The majority of laser types in current use produce output beams with circular or elliptical cross-sections, with either Gaussian or near-Gaussian intensity profiles. This Gaussian intensity distribution is acceptable, and often beneficial for many applications in which the laser beam is being focused to a small spot. However, there are also many different uses for whic...
متن کاملEfficient mode transformations of degenerate Laguerre-Gaussian beams.
We present an approach for efficient conversion of a single-high-order-mode distribution from a laser to a nearly Gaussian distribution and vice versa. It is based on dividing the high-order mode distribution into equal parts that are then combined together coherently. We implement our approach with several optical arrangements that include a combination of discrete elements and some with singl...
