摘要
从理论上估算了O_2 (~1△_g)二聚物激光输出功率,在实验中以微波(2.450GHz)激励高纯氧产生0_2(~1△_g)二聚物,采用平凹稳定谐振腔,首次在波长6561nm处实现了O_2(~1△_g)二聚物的激光振荡,当充入氧气压强为133.3pa,微波激励功率为600W时,激光输出功率可达100μW,此结果在数量级上与理论估算相同.另外还测得激光束散角约37.3mrad.
The laser output power of the dimer of O2 (1Δg) was estimated theoretically. By means of microwave (2.450GHz) exciting high pure oxygen to generate the dimer of O2(1Δg) in experiments, the laser oscillation of the dimer of O2(1Δg) was realized at 656 nm for the first time with stable flat-concave resonator. When the pressure of oxygen was 133.3Pa, the power of microwave was 600W, the laser power was as high as 100 μW, this corresponded to theorectical estimation in order of magnitude. In addition, the diverge angle measured was about 37.3 mrad.
