Appendix F: Waist Radius Measurement of Gaussian Beams
ثبت نشده
چکیده
OI-RD microscopes scan focused Gaussian laser beams across a microarray to provide spatial maps of the reflectivity difference. I review some properties of Gaussian beams, with particular emphasis on the waist diameter, which governs the best resolution achievable with an OI-RD microscope. Data is presented demonstrating a scanning knife-edge method for measuring a Gaussian beam waist; this method was used to measure the waist diameter for several OI-RD microscopes.

Wave dislocation reactions in non-paraxial Gaussian beams
For exact (i.e., non-paraxial) waves 1c, representing freely propagating Gaussian beams in two and three dimensions, the patterns of phase singularities, that is zeros of 11,, are studied in detail. The zeros (points in two dimensions, and rings in three) are phase dislocations (optical vortices). The waves depend on a single parameter L , representing the radius of the waist of the beam. As L ...
متن کاملOrbital angular momentum of Laguerre-Gaussian beams beyond the paraxial approximation.
We derive a full field solution for Laguerre-Gaussian beams consistent with the Helmholtz equation using the angular spectrum method. Field components are presented as an order expansion in the ratio of the wavelength to the beam waist, f=λ/(2πw₀), which is typically small. The result is then generalized to a beam of arbitrary polarization. This result is then used to reproduce the signature an...
متن کاملPropagation of axially symmetric flattened Gaussian beams
Flattened Gaussian beams are characterized by a waist profile that passes in a continuous way from a nearly flat illuminated region to darkness. The steepness of the transition region is controlled by an integer parameter N representing the order of the beam. Being expressible as a sum of N Laguerre–Gauss modes, a flattened Gaussian beam turns out to be very simple to study as far as propagatio...
متن کاملGaussian Beam Modeling of the Radius of Curvature
A Gaussian model of the radius measurement of micro-optics has been developed and tested using simulations. The model is based on the propagation distances in the interferometer, a heretofore uninvestigated effect. The goal of the model is to determine the bias error in the radius due to the Gaussian Beam propagation model. After testing the model with varying conditions, we have concluded the ...
متن کاملApplication of Hertz vector diffraction theory to the diffraction of focused Gaussian beams and calculations of focal parameters.
Hertz vector diffraction theory is applied to a focused TEM00 Gaussian light field passing through a circular aperture. The resulting theoretical vector field model reproduces plane-wave diffractive behavior for severely clipped beams, expected Gaussian beam behavior for unperturbed focused Gaussian beams as well as unique diffracted-Gaussian behavior between the two regimes. The maximum intens...
