New Donor - Acceptor Chromogene Laser Dyes Generating In The Visible Spectral Range

Abstract

Lasing properties of 20 new dyes generating in 480-705 nm spectral range under pulsed nitrogen laser exitation are presented. Dyes with donor - acceptor chromogene are of the main importance in the laser techniques. The best known as Coumarines, Rhodamines or Oxazines etc. are widely used for generation of a tunable laser light in a whole visible spectral range. In this paper we would like to present lasing properties of four new groups of this kind of dyes. General structures of presented groups of dyes are shown in Figures 1 (a-d). In Table 1 full chemical names as well as radicals for all the dyes are given. The methods of the chemical synthesis of these dyes were described in our previous papers.
