A MULTIWATT ALL GAS-PHASE IODINE LASER (AGIL)

摘要

The demonstration and characterization of a multiwatt All Gas-phase Iodine Laser (AGIL) are described. A 20-cm subsonic reactor was used to produce NCl(a~1Δ) for a series parametric studies of the I~*(~2P_(1/2)) - I(~2P_(3/2)) small signal gain and extracted power dependence on reactant flow rates and reaction time. A reduction in the flow channel height led to improved performance. The highest measured gain was 4.2 x 10~(-4) cm~(-1) and the highest power observed was 31 W.
