Stokes, E. D. published the artcileHigh efficiency dye laser tunable from the UV to the IR, Application of 5,9-Diaminobenzo[a]phenoxazin-7-ium acetate, the publication is Optics Communications (1972), 5(4), 267-70, database is CAplus.
A dye laser was developed as a source of tunable radiation at 3500-7300 ?. A variety of dyes and dye mixtures were used to cover this range. Output powers ¡Ü30 kW were obtained with line widths <1.8 ?. A Fabry-Perot etalon reduced the output line width of 0.1 ? and the peak output power by a factor of 3. Second harmonic powers in excess of 2 kW were generated from the output of this laser. The efficient 2nd harmonic generation extended the lower wavelength limit to 2442 A. A N laser was used as pumping source.
