摘要：
The characteristics of Nd:YAG laser pumped energy transfer distributed feedback dye laser (ETDFDL) is studied theoretically and experimentally in a mixture of Rhodamine 6G and Acid blue 7 dyes. The characteristics of donor DFDL, the acceptor DFDL, the dependence of their pulse width and output power on donor-acceptor concentrations. pump power and lengths of the excited region are studied. Experimentally the output energy of DFDL is measured at the emission peak of donor and acceptor for different pump powers. donor, acceptor concentrations and length of the active medium. In addition, the tunability of DFDL emission both in donor and acceptor emission ranges is measured. (C) 2002 Elsevier Science B.V. All rights reserved.
