通过Abinitio计算证明O2(1Δg)二聚物具有D2h群构型。利用微波激励高纯氧获得了O2(1Δg)二聚物的2个新谱带,它们的峰值波长分别为486nm和656nm。采用放大自发辐射法获得了486nm和656nm辐射的小信号增益系数;利用平凹稳定谐振腔获得了486nm和656nm辐射的激振荡,最大激光输出功率分别为了130μw和140μw,束散角为28mrad。
Calculations by Abinitio demonstrated that the O2 (1 [Delta] g) dimer has the D2h group configuration. Two new bands of O2 (1Δg) dimers were obtained by microwave excitation of high purity oxygen, with peak wavelengths of 486 nm and 656 nm, respectively. The small-signal gain coefficients of 486nm and 656nm radiation were obtained by using the amplified spontaneous emission method. The excited oscillations of the 486nm and 656nm radiation were obtained by using the plano-convex stabilized resonator. The maximum laser output power was 130μw and 140μw respectively, and the beam divergence angle was 28mrad.
