چکیده
A method of calculating the angular alignment tolerance of a Porro prism laser oscillator is presented. The reduction in mode volume due to misalignment is found by a ray optical approach. An analytical expression for alignment tolerance, in terms of resonator length L, prism azimuth angle theta, rod location L(2), and rod aperture radius alpha is obtained. An experiment was set up to measure the laser output reduction due to reflector tilting. Results obtained are in good agreement with the theoretical predictions.

Kaleidoscope modes in large aperture Porro prism resonators.
We apply a new method of modeling Porro prism resonators, using the concept of rotating loss screens, to study stable and unstable Porro prism resonator. We show that the previously observed petal--like modal output is in fact only the lowest order mode, and reveal that a variety of kaleidoscope beam modes will be produced by these resonators when the intra--cavity apertures are sufficiently la...
متن کاملStudy of Effects of Wave Plate Orientation in Cross Porro Prism Diode Pumped Nd:yag Laser Resonators
In this paper the two different configurations of Porro prism resonators using Jones matrix method are studied theoretically. In one of the configurations the Q-switch is kept in the output arm while the gain medium is kept in feedback arm. In the other configuration, Q-switch and gain medium is kept in the feedback arm. The roundtrip Jones matrix for both the configurations are calculated and ...
متن کاملTilting tolerance analysis of a broadband polarization-preserving beam displacer.
We numerically investigated the performance of an achromatic polarization-preserving beam displacer that was proposed by Galvez [Opt. Lett.26,971(2001)]. First, the four-prism configuration of the Galvez scheme is verified by simulation. We examined the extension of wavelength beyond visible light by considering the corresponding power loss. The degree of polarization is also considered. The to...
متن کاملPetal-like modes in Porro prism resonators.
A new approach to modeling the spatial intensity profile from Porro prism resonators is proposed based on rotating loss screens to mimic the apex losses of the prisms. A numerical model based on this approach is presented which correctly predicts the output transverse field distribution found experimentally from such resonators.

The buried hetero-structure (BH) InGaAsP-InP waveguide is used for asystem of double microring resonators (DMR). The light transmission and location ofresonant peaks are determined for six different sets of ring radii with different ordermode numbers. The effect of changing middle coupling coefficient on the box likeresponse is studied. It is found that the surge of coupling coefficient to the ...
