高繰返し固体レーザ用キセノンフラシュランプの長寿命化

抄録

The lifetime of Xe flashlamp was tested by changing the geometrical shape and materials of electrode, and the fused silica tubes with and without large amount of OH base.
Tungsten was best material as a electrode, because the deterioration of fused silica tube caused by electrode evaporation due to flashlamp discharge at high repetition-rate was minimum. The lifetime of Xe flashlamp was lengthened by using the fused silica tube with high thermal conductivity.
