Diffraction losses for symmetrically tilted plane reflectors in open resonators
Applied Optics, 1980Diffraction power losses for tilted (open) resonators with both circular and strip flat reflectors are computed for several tilt angles by means of a second-order perturbation technique. Results indicate that the power losses increase as the square of the perturbation parameter. The strips exhibit a greater additional power loss per transit for the TEM(

Diffraction losses of Nd:YAG and Yb:YAG laser crystals
Optics & Laser Technology, 2001Abstract Based on space-dependent rate equations, the lowest threshold input power for a diode end-pumped solid-state laser is obtained for the pump spot size w p →0. However, as the pump beam waist is decreased, the thermally induced effects in the laser rod would be very high.

Diffraction losses of high power solid state lasers
Optics Communications, 2001Abstract A uniform pumping distribution is very important in a side pumped rod geometry. Based on space-dependent rate equations, the threshold pump power and the TEM 00 mode output power of a solid state laser with a uniform pump are obtained. The diffraction losses arising from thermally induced spherical aberration have been estimated by the ...

Resonant diffraction losses in solid-state monomode lasers
Journal of the Optical Society of America B, 2001The mechanism of resonant diffraction in solid-state lasers is theoretically investigated and experimentally isolated. It consists in a variation of the diffraction losses of a laser with the laser frequency, which is induced by a frequency-dependent saturation lenslike effect that occurs in the active medium.

Diffraction losses in a laser-heated solenoid plasma
Journal of Applied Physics, 1975A solution for diffraction loss of a laser beam propagating in a plasma light pipe is found by analogy to the tunnel effect of quantum mechanics. It is shown that diffraction tends to dissipate the beam layer by layer, working from the outside inward. A characteristic dissipation length can be defined for each layer of the beam.

Diffraction loss in radiometry
Applied Optics, 2003Diffraction loss in radiometry has gained in importance recently because of an increased interest in longer wavelengths and the continuous improvement in experimental accuracy. The deviation from geometrical optics now contributes significantly to the errors of experiments.

IEEE Transactions on Magnetics, 1987
The present paper reports theoretical computations of the diffraction loss incurred by magnetostatic forward volume waves (MSFVW's) with propagation in a YIG film as a result of the finite length of the radiating transducer. As in the case of magnetostatic surface waves (MSSW's), this loss is found to decrease with increasing frequency, a feature that ...
