This work continues the authors' research about mutual transformations of Hermite-Gaussian and Laguerre-Gaussian beams by astigmatic optics. Recently, a parametrical beam family, which contains HG… (More)
A generalization of ABCD matrix rule for transformation of a higher Gaussian beam in general astigmatic optical systems is proposed. This way is simpler than direct Fourier integral calculation and… (More)
The new results concerning spiral beams and their applications are considered.
Of a high interest now are the light fields with spatially inhomogeneous polarization state. These fields give new possibilities for many aspects of optical science and engineering. We consider a new… (More)
Hermite-Laguerre-Gaussian beams are paraxial structurally stable solutions of the parabolic equation. Some relations of these beams with fractional Fourier transform and the convolution… (More)
Spiral beams are paraxial structurally stable rotating wavefields. For any planar curve there are such spiral beams, whose intensity shape is similar to the curve. The usage of Gerchberg-Saxton… (More)
Spiral beams are structurally stable laser beams, which intensity remains the same within scale and rotation as they propagate. Last years, a family of spiral beams with intensity structure shaped… (More)
The structurally stable light fields with rotation under propagation is considered. Some examples of practical applications are shown.
Hermite-Laguerre-Gaussian beams and spiral beams are the wave fields, whose intensity is structurally stable under propagation in Fresnel diffraction zone and focusing. The only difference between… (More)
