    Dynamics of low-pressure gain-switched iodine lasers (1995)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 67 (1995), S. 464-466

    Topics: Physics
    Notes: The dynamics of gain-switched, low-pressure photolytic iodine lasers were investigated experimentally and theoretically as a function of pressure and buffer gas. The behavior of the pulse shape, build-up, and duration can be explained by relaxation from a nonthermalized to a thermalized velocity distribution of the gas. © 1995 American Institute of Physics.

    Using laser pulse dynamics to probe the relaxation of an anisotropic velocity distribution of excited iodine (1996)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 104 (1996), S. 3537-3545 
    Details

    Topics: Physics , Chemistry and Pharmacology
    Notes: The pulse characteristics of a photolytic, gain-switched iodine laser are a sensitive measure for relaxation processes that occur in the active medium. On a time scale shorter than a few microseconds this concerns the relaxation of the speed and the angular parts of the anisotropic velocity distribution which is produced by the photodissociation of the parent molecule CF3I. A comprehensive rate equation model of the laser dynamics is fit to experimental data, to obtain time constants for these collision-controlled relaxation processes for various buffer gases and pressures. © 1996 American Institute of Physics.

    Generation of high-number densities of iodine monofluoride in a supersonic flow (1989)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 66 (1989), S. 6093-6097 
    Details
    ISSN: 1089-7550

    Topics: Physics
    Notes: Iodine monofluoride, a promising visible chemical laser candidate, has been chemically produced at number densities exceeding 1×1015 molecules/cm3 in a supersonic flow. Combustion of nitric oxide and molecular fluorine produced atomic fluorine at an efficiency of 20%–30%, independent of flow conditions. The subsequent transonic reaction of atomic fluorine with molecular iodine to produce a stable flow of IF(X1Σ+) was mixing limited and complete within 10 μs. The low-pressure (3 Torr), low-temperature (300 K) flow environment should be suitable for lasing.

    Magnetic Q-switching of a photolytic iodine laser (1989)
    Springer
    Applied physics 48 (1989), S. 357-364 
    Details
    ISSN: 1432-0649

    Topics: Physics
    Notes: Abstract The Zeeman effect has been utilized in a switching technique of an atomic iodine laser. Magnetic fields up to a kilogauss have been applied to atomic iodine, prepared by thermally dissociating molecular iodine, that was situated inside the laser cavity. The absorption of the 1.315 μm light by atomic iodine was reduced by approximately 90% when the field was applied. This effect is used here to demonstrate a gas phase, self-healing Q-switch for a small (1 mW) cw photolytic iodine laser. Enhancement ratios of pulse power over cw power on the order of 55 to 1 were achieved.

    Notes: Abstract The output of a chemical oxygen iodine laser (λ=1.315 μm) has been frequency doubled at an overall conversion efficiency of ≃1%. A lithium iodate (LiIO3) crystal was used in an intracavity doubling scheme. This represents the first time visible laser light has been obtained, solely from a chemical source.
