Herein the authors report on the demonstration of a 95% enhancement in continuous-wave laser power on the 1315 nm transition of atomic iodine via a 50% increase in gain length, flow rates, and discharge power. O2(a 1Δ) is produced by a single radio-frequency-excited electric discharge sustained in an O2–He–NO gas mixture flowing through a rectangular geometry, and I(2P1/2) is then pumped using energy transferred from O2(a 1Δ). A gain of 0.26% cm-1 was obtained and the total laser output power was 54.8 W.

    In associative desorptions governed by short-range forces, strong energy transfers between rotational, translational, and vibrational degrees of freedom of the nascent molecule take place beyond the transition state (TS). State or energy distributions are thus different at the TS and in the...

    In this work we report a novel methodology that is able to predict how energy transfer transition probability density functions [P(E′,E)] change with the maximum impact parameter (bmax) used in trajectory calculations (TC’s). The method assumes that P(E′,E) can be described by...

    A generic model of an endoreversible engine is developed for studying the effect of convective heat transfer, the rate of which depends on the temperature difference to the power n where n is close to unity. The efficiency at maximum power production is found to have as its principal part the...
