Fabrication of Compact Ruby Laser and its Operation Characteristics

플라즈마 진단용 소형 루비레이저의 제작과 동작특성에 관한 연구

In this paper, design feature and operation characteristics of compact Ruby laser for plasma diagonostics are described. A linear Xe flashlamp and a single elliptical cavity are adopted as optical pumping system. With charging energy of 484J, the maximum output energy of 170mJ, laser pulse width $110{\mu}s$, and slope efficiency 0.09% were obtained. If Q-switch system is added to this laser, we suppose this laser will be quite enough for diagonizing plasma.
