    Abstract: An infrared source producing a coherent output having a spectrally narrow and continuously tunable frequency is described. Such a source uses a four wave mixing process in an alkali metal vapor, wherein the initial input beams to the alkali metal vapor come from two dye lasers. In an alternative mode of operation, tunable ultraviolet output is obtained.

    Abstract: An optically pumped organic laser using materials having allowed electric dipole fluorescent transitions. These materials include photosensitizing dyes. The active fluorescent materials are pumped with either a laser pulse or a flashlamp pulse, the pumping pulse having a risetime not exceeding a few times the decay time between the first excited singlet state and a triplet state of the fluorescent material.
