Laser using the vapor of complex organic compounds
Abstract
Study of the effect of an extraneous gas on the frequency and other characteristics of the generated emission of 1,4-di/2(5-phenyloxazolyl)/-benzene (POPOP) vapor. A study is made of the dependence of the frequency of the maximum of the generated emission band and the maximum of the POPOP vapor fluorescence spectrum on the concentration of the extraneous gas centane used to obtain stable emission of POPOP vapor. At centane pressures of the order of 1 atmosphere emission is found to occur in a single band at 383 nm (close to the 0-1 electronic-vibrational band at 379 nm). At centane pressures of 3 to 8 atm, however, a two-band emission (at 383 and 403 nm) is observed. The occurrence of emission at the 403-nm wavelength is attributed to an increase in the relative intensity of the 0-2 electronic-vibrational band at these centane pressures and to broadening of the absorption spectrum.
