Sodium-Mercury Excimer Laser. Phase 1

Abstract

This Phase I work addresses the technology required to test the sodium-mercury excimer laser concept. Calculations of the optimum laser excitation conditions show that a gain of 2.8% /cm should be achievable in the 1.2 micron region for a specific discharge power input of 20kW/cu cm. At the lower power input of 2kW/cu cm the projected gain is 1.5%/cu cm. The calculations consider the electron energy distribution function and collisional dissociation of NaHg(A) state molecules. Ultraviolet pre-ionisation was shown to be a viable route to the attainment of high power discharges in this system. An experimental test of 600 deg C cell technology was performed, in which windows, lead-throughs and a close-out valve were cycled repeatedly to that temperature.. ..
