Abstract:
A dye laser for generating laser pulses of long duration comprising an optical resonator which comprisesan elongated dye cell comprising a space which is defined by two elongated and substantially parallel main surfaces and by side and end surfaces connecting the main surfaces and containing a light gain medium that can be excited to population inversion, the distance of the main surfaces from each other being substantially smaller than their length in the longitudinal direction of the dye cell, and the outputs of the laser pulses from the dye cell being formed by said end surfaces;mirrors placed in optical connection with the outputs of the laser pulses of the dye cell, at least one of the mirrors being partially transmissive for feeding the laser pulse out; andmeans comprising at least one elongated gas discharge lamp arranged in the longitudinal direction of the dye cell for feeding excitation light into the dye cell so that the excitation light periodically sweeps across the cell in the lateral direction of the cell as a function of time.
