Issue Date: | 16-Jul-2001 | Publisher: | American Institute of Physics | Citation: | Applied Physics Letters 79(3): 305 (2001) | Abstract: | We report on the lasing action of modified dipyrromethene BF2 complexes in air-equilibrated liquid solutions. All recent dyes share a common chromophore core and were dissolved in apolar, polar nonprotic, and polar protic solvents. When pumped transversely at 534 nm, nearly solvent-independent laser emission was obtained with efficiencies well over 40% in most cases. Highest lasing efficiency was 59%. Under continuous ultraviolet irradiation some of these dyes demonstrated improved photostability as compared with commercial dye pyrromethene 567. | Description: | 3 pages, 2 figures, 1 table.-- The materials described in this letter and their utilization in solid-state dye lasers are covered by Spanish Patent No. 9 901 540, filed on July 9, 1999.-- PACS: 42.55.Mv; 42.60.Lh | Publisher version (URL): | http://dx.doi.org/10.1063/1.1385185 | URI: | 10261/21616 | DOI: | 10.1063/1.1385185 | ISSN: | 0003-6951 |
