Abstract
Two-photon pumped cavity lasing is firstly operated based on an organic dye , trans-4-[p-(pyrrolidinyl)styryl]-N-methylpyridium iodide, using mode-lock ed picosecond laser beam at 1064 nm as pump source. There is an obvious blu e shift for the central wavelength of cavity lasing compared with that of t he two-photon absorption (TPA) induced fluorescence. This phenomenon is exp lained by using the difference of the re-absorption coefficient at differen t condition. The lifetime of the fluorescence is measured to be 89 ps. The temporal properties of TPA induced cavity lasing are measured and obvious o scillations can be obtained. (C) 2001 Elsevier Science B.V. All rights rese rved.
