Resonant Modes in a Maser Interferometer

Investigation of Quasi-Optical Bessel-Gauss Resonator at Mm- And Submm-Wavelengths

“…It is well known that in optics the classical Fox-Li iterative algorithm [24] is quite competent to calculate the field distributions in optical cavity. It employs the scalar form of the Kirchhoff formula for diffraction to analyze the resonating modes and therefore is appropriate for the analysis of the cavity at light wavebands.…”

Laser Beam Diagnostics in a Spatial Domain

“…where n is the refractive index of the lens, 0 T is the center thickness of the lens, and ( ) 11 , Tx y is the thickness function of the lens at a position ( 1 x , 1 y ). By considering the geometry of the lens in Fig.…”

Hole Gratings and Diffraction of Gaussian Beams.

“…For the case in which ten holes are strongly (1) Let us envision the different diffractional orders illuminated, the relative errors in the 0-1 interval, using as being comprised of individual beams nominally interference terms corresponding to (0,1), (-1,0), and propagating away from the grating at angles given by (1,2), the relative errors are reduced at all points to mX/d for the mth order, X being the optical wavelength, within 0.3%. Because the centers of curvature of the individual beams lie on lines connecting each diffractional beam V. Fraunhofer Diffraction of Gaussian Beams with the grating but do not coincide with the grating, the Consider a Gaussian beam traveling in the + direccenters of curvature for the outgoing mth order beams tion with its waist at r = 0, having an intensity proare distinct.…”
