PURPOSE:To obtain a dye laser device where excitation of high efficiency that is not realized in a conventional laser device can be attained by a method wherein excitation laser rays are separated into wavelength components effective for the excitation of dyes, the laser rays separated into wavelength components are so constituted as to excite the correspondent dye cells, and dye of adequate concentration highest in efficiency or the excitation laser rays is applied to the dye cell concerned. CONSTITUTION:Copper vapor laser rays are separated into light rays of two wavelengths G and Y, the separated light rays G and Y in wavelength are made to irradiate dye cells 14 and 15 respectively, provided that the dye concentrations of a first dye cell 14 and a second dye cell 15 excited by the laser rays of G and Y in wavelength are represented by Na and Nb respectively, and the separated excitation rays G and Y in wavelength are made to enable a dye laser device to most effectively output dye laser rays B. That is, the dye concentrations Na and Nb which make an excitation dye concentration N1 maximal are so set as to satisfy following formulas, Na=1/sigmag(lambdaG).D[cm<-3>], Nb=1/sigma(lambdaY).D[cm<-3>], where Na and Nb are dye concentration [cm<-3>], sigmag(lambdaG) and sigmag(lambdaY) denote the light absorption cross sectional area [cm<-2>] of dyes to rays G and Y in wavelength, and D represents the width [cm] of an excitation converged light. |
