Iodine Laser.
Abstract
There has been a project at the Naval Postgraduate School for the past two years to build a high power, short pulse, Iodine Photodissociation Laser to be used for plasma and nuclear fusion related research. The first attempt, reported previously, met with difficulties. This paper details the changes made to the previous system in order to achieve a working laser. Lasing was observed for the first time on 31 January 1977. First shot energies up to 150 milljoules have been obtained in a pulse length of 15 microseconds. Investigation was carried out on the reduction in output energy with repeated shots on the same gas filling. The rate of deterioration was shown to increase with increasing fill pressure and to be caused mainly by the formation of molecular iodine. Removal of the molecular iodine between shots significantly reduced the deterioration rate. (Author)
