Розробка і дослідження СММ лазера на основі КХР з модовим селектором Head Svich V.A., Registration Date 27-03-2002 Organization Kharkov National University named after V.N.Karazin popup.description2 The quasioptical waveguide resonators, the methods of shaping of the output radiation beams with the uniform intensity profile, the transverse mode selection methods and also lasers on the basis of such resonators are the object of the investigation. The purpose of the work is numerical research of shaping of output beams with the homogeneous intensity profile in quasioptical waveguide resonators (QWR) with nonuniform mirrors; development and making of the wide-band submillimeter laser with the optical pumping on the basis of the QWR with the coupling holes in the mirrors and selector of the transverse modes. The theoretical model and the algorithm of calculation on the basis of Fourier optic methods are developed in this work. The numerical investigation of shaping of the output radiation beams with the uniform intensity profile in the QWR with the amplitude spatial filter on one of the mirrors is carried out. The requirements of Fourier modeexistence and its stability characteristics are established by changing of the resonator geometry and the nonuniform reflector parameters. The investigation results can be used in designing and making of the waveguide lasers with an output quasiuniform intensity profile, and also wide-band monomode lasers of the submillimeter wave range.
