  • Variable frequency short cavity dye laser
    Patent number: 4751712
    Abstract: A dye laser system especially useful for generating short pulses in response to excitation laser pulses directed to an appropriate dye contained between opposing mirrors that form a short cavity within a small, easily replaceable cell. The spacing of the mirrors is adjustable by application of a force from outside of the cell, thereby allowing control of the frequency of the laser output. The cell is self-contained, including a dye reservoir maintained in continuous liquid communication with the cavity for providing fresh dye to it.
