Abstract : The original objective of this investigation was the development of efficient 2-meter long coaxial laser lamps capable of withstanding input energies up to 135 kilojoules. Since most of the available laser rods were only 1-meter in length, and because design improvements could be more effectively accomplished with shorter lamps, the development of 1-meter lamps was emphasized. Use of these coaxial flash lamps has resulted in a rate of conversion of electrical energy to laser output energy (slope efficiency) of 5.1 percent; this efficiency is comparable to that reported for the most efficient pumping geometry employing linear lamps when used to excite the same laser rod. A filament-wound coaxial flash lamp has successfully and repeatedly withstood energy loadings of 150,000 joules in 2-3 millisecond pulse lengths. Steps are described which can be taken to improve the efficiency, energy loading capability, and reliability of the lamps. (Author)
