摘要

研究了光泵浦亚稳态稀有气体激光器（OPRGL）。首次产生了基于Ne - he混合物中亚稳氖（Ne*）原子在脉冲体制下的横向光抽运激光。在频率为200khz的纳秒重复脉冲辉光放电等离子体中产生Ne*。用染料激光器提供脉冲光泵浦，波长对应于155→2p9 （640.2 nm）和155→2p8 （633.4 nm）的氖跃迁。实验确定了各种增益介质参数对激光特性的影响。利用155→2p9和155→2p8跃迁的光泵强度测量Ne* -He OPRGL生成阈值。

Lasing on Metastable Neon Atoms with Pulsed Transverse Optical Pumping

Optically pumped metastable rare gas lasers (OPRGL) have been investigated. Lasing based on metastable neon (Ne*) atoms in a Ne–He mixture in a pulsed regime with transverse optical pumping was produced for the first time. Ne* was produced in the plasma of a nanosecond repetitively pulsed glow discharge with a frequency of 200 kHz. Pulsed optical pumping was provided by a dye laser at wavelengths corresponding to neon transitions of 1s₅ → 2p₉ (640.2 nm) and 1s₅ → 2p₈ (633.4 nm). The effect of various gain medium parameters on lasing characteristics was experimentally determined. Ne*–He OPRGL generation thresholds were measured by optical pump intensity of 1s₅ → 2p₉ and 1s₅ → 2p₈ transitions.
