The open resonator eigenmodes may be determined by solving the free-space Maxwell equations with perfect conductor boundary conditions on the mirrors. In the practice usually the Fresnel approximation is made for formulating the problem in the form of the well-known Fresnel-Kirchhoff equation. The solutions to this equation are generally not obtainable analytically. Numerical methods are applicable in the practice only at relatively small Fresnel number. For larger Fresnel number asymptotic methods have been developed which are good in the highly unstable region. However this asymptotic technique fails for marginally unstable resonators. In the stable region the eigenmodes are well described by Gaussian-Hermite solutions, which also become less accurate as the resonator becomes marginally stable. Thus, there is an area between the stable and unstable regions where neither the Gaussian beam theory nor asymptotic solution is valid.","PeriodicalId":265943,"journal":{"name":"Proceedings of LFNM'2000. 2nd International Workshop on Laser and Fiber-Optical Networks Modeling (Cat.

The measurements which we carried out have shown that the proton donating solvents have the greatest influence on the absorption-fluorescence parameters and spectral-power lasing characteristics of these derivatives. In which case the dye molecule structure exerts essential influence over intermolecular interactions of the excited benzopyrone derivative molecule with environmental solvent molecules, which occur in the solution. So, for example, the rigid fixation of the diethylamino group in the molecule structure of the investigated derivatives results not only in the long-wavelength shift of the absorption, fluorescence and lasing spectra, but also changes the non-radiative deactivation processes of the electron excitation of the molecule in the high singlet state in the proton-donating solvents. Derivatives with the free diethylamino group reduce the lasing energy sharply in such solvents, and ones with this group fixed rigidly in the molecule structure-increase it.","PeriodicalId":265943,"journal":{"name":"Proceedings of LFNM'2000. 2nd International Workshop on Laser and Fiber-Optical Networks Modeling (Cat.
