Abstract
Solid state and dye lasers of a new ype are developed which permit to get a multicolor radiation in a superbroad spectral region. These lasers possess a number of peculiarities and d istinc­ tions from common ones: the resonator is used , which forms the correspondence of the active medium pointB and their image after each full pass of the radiation through the resonator; a new method of a lasing speci:,rum tuning is used ; the gain narrowing is violated. These pecularii:,ieB give the ability to form a desirable spectral distribu­ -c ion of the output energy in "the spec"tral region from violet to red. A simultaneous lasing at three or more independently "'t.unable lines is possible. Their relative intensities can be opera-Ced independently also. It is shown experimentaly , that it is poseible to change the linewidth and to get lasing at several tunable pa.rte of the continuum or to get continuous spect.rum with the width up to 0 . 6 - 0 . 8 of the luminescence spectrum of the active medium. The Theoretical model of the new lasers is developed. The spectral characteristics of the output radiation of lasing are calculated n different situations. The cavities of such a type lasers are investigated by the matrix optics method. The main properties of these lasers are investigated experimentally.
