Abstract
Operation of a multiple pulse lengths distributed feedback dye laser is reported. Solution of Rh6G in ethanol (1mM) was pumped by the five pairs of second harmonic of a passively modelocked Nd:YAG laser. The time delays among pump pulses were varied within coherence length. The wavelengths were tuned by microcontroller based stages. Number of lasing lines varied from minimum five to seventeen (540-590nm) at pulse lengths of 2 to 40ps.
