描述了最近使用大阪大学激光工程研究所的 Gekko MII 玻璃激光设备进行的软 X 射线激光实验。使用约 100 J 能量的线聚焦 532 nm 激光辐射爆炸的箔靶，研究了重组等离子体中的氢和类锂激光方案。在一项初步研究中，发现C/sup 8+/和O/sup 7+/中的巴尔默-α跃迁以及Al/sup 10+/中的5-3跃迁的时间积分发射随着靶长度的增加而非线性增加，产生G=0.9至2.3 cm/sup -1/的增益系数。在随后的更精细的研究中，包括时间分辨测量，作者获得了 G=2 cm/sup -1/ 的增益和 F/sup 8+/ 在 80.9 AA 下巴尔默-α 跃迁的增益长度乘积 GL=3。 >
Soft X-ray laser experiments recently carried out using the Gekko MII glass laser facility at the Institute of Laser Engineering, Osaka University, are described. Hydrogenic and lithiumlike lasing schemes in recombining plasmas were investigated using foil targets exploded with line-focused 532 nm laser radiation of approximately 100 J energy. In a preliminary study, time-integrated emissions of Balmer- alpha transitions in C/sup 8+/ and O/sup 7+/ and 5-3 transitions in Al/sup 10+/ were found to increase nonlinearly with increasing target length, yielding gain coefficients of G=0.9 to 2.3 cm/sup -1/. In a subsequent, more refined study, which included time-resolved measurements, the authors obtained a gain of G=2 cm/sup -1/ and a gain-length product GL=3 for the Balmer- alpha transition in F/sup 8+/ at 80.9 AA. >
