Abstract : A free expansion nozzle for gas dynamic lasers having a multitude of finely divided free expansion sites. These sites may be in the form of a plurality of minute openings within a plate, or minute spacings between adjacent cylinders, or in the form of a small mesh screen. In any case these expansion sites may be situated within the nozzle section of a gas dynamic laser, thereby providing an easily fabricated, economical means of producing a lasing medium within the optical cavity of the laser.
