A novel, repetitively pulsed, photolyticQ-switching scheme has been demonstrated on a 1.315 μm (2P1/22P3/2) cw photolytic iodine laser using an intracavity cell containing either IBr or ICl. When the cell is irradiated with a KrF laser (λ=248 nm), I(2P3/2) atoms are produced and lasing ceases due to the introduction of loss into the laser cavity. Lasing resumes, however, following recombination of the atoms into the parent molecule. Experimental evidence is presented which indicates that the laser's shut-off time is a function of excimer laser energy and the pressure of buffer gas in the cell.
