Abstract
A comparison of the performance of pulsed infrared HF lasers pumped by phototriggered discharges using either Ne/SF6/H2 or Ne/SF6/C2H6 mixtures are presented. For an active volume of 50 cm3, a specific output energy as high as 11 J/ℓ has been achieved with an efficiency higher than 3% when C2H6 is used as H atom fuel. The replacement of ethane by molecular hydrogen reduces the laser performance by 40%. The investigation of the temporal evolution of the laser intensity shows that this dramatic decrease results from a shortening of the laser pulse duration rather than from a decrease of the peak power. Indications are given that this behavior is correlated to a very different temporal evolution of the discharge parameters, especially at low reduced electric field E/N.
