Efficient energy transfer dye lasers in spectral region of near ultraviolet to violet
Abstract
An experiment was performed on the operation and development of energy-transfer dye lasers (ETDL), using scintillator dye mixture to obtain higher efficiency and an expanded range of wavelengths in the ultraviolet-to-violet region, in which an N2 laser is used for excitation. High lasing efficiencies were observed with alpha NPO dimethyl POPOP, PPF/alpha NPO, and some other dye mixtures; and overlapping lasing was observed, involving the donor and acceptor dye-laser regions. A blue shift of the oscillation frequency was analyzed theoretically, and the theoretical results concerning the dependence of the oscillation wavelength on laser power and donor dye concentration were in good agreement with observations.
