Transverse effects in multifrequency Raman generation (2000)
Journal Article
Syed, K., Mcdonald, G., & New, G. (2000). Transverse effects in multifrequency Raman generation. Journal of the Optical Society of America B, 17(8), 1366-1375. https://doi.org/10.1364/JOSAB.17.001366

The theory of ultrabroadband multifrequency Raman generation is extended, for the first time, to allow for beam-propagation effects in one and two transverse dimensions. We show that a complex transverse structure develops even when diffraction is ne... Read More about Transverse effects in multifrequency Raman generation.

Kaleidoscope laser (2000)
Journal Article
Mcdonald, G., Karman, G., New, G., & Woerdman, J. (2000). Kaleidoscope laser. Journal of the Optical Society of America B, 17(4), 524-529. https://doi.org/10.1364/JOSAB.17.000524

We report the first calculations of mode patterns of unstable-cavity lasers with truly two-dimensional transverse geometries. A detailed account of numerical techniques, incorporating a nonorthogonal beam-propagation method, and results for cavities... Read More about Kaleidoscope laser.

Propagation properties of nonparaxial spatial solitons (2000)
Journal Article
Chamorro-Posada, P., Mcdonald, G., & New, G. (2000). Propagation properties of nonparaxial spatial solitons. Journal of Modern Optics, 47(11), 1877-1886. https://doi.org/10.1080/09500340008232440

We present an analysis and simulation of the non-paraxial nonlinear Schroedinger equation. Exact general relations describing energy flow conservation and transformation invariance are reported, and then explained on physical grounds. New instabiliti...
