Abstract : The overall objective is to produce more efficient cw and pulsed optical pumps for Nd:YAG lasers. Both noble gases and alkali-metal vapor are being studied. The development of the alkali discharge as a cw pump has concentrated on optimizing the spectral output by varying the pressure. A potassium and rubidium filled lamp was found to give the best overlay with the absorption bands of Nd:YAG. Noble gas discharges have been investigated as pulse pumps. Xenon and krypton have been compared at input energies of 5, 10, and 20 joules, bore diameters of 3, 4, and 5 mm, gas pressures of 450, 700, 1500, and 3000 torr. Krypton was generally found to be approximately 20% more effective in exciting Nd:YAG. (Author)
