| 摘 要： | 用二维光学多道分析仪考察了He-Ne激光器在632.8nm激光振动和不振荡时氖能级3s_2和2p_k(k=1,2,……8,10)的侧光辐射,进行了Abel反演后,得到了3s_2和2p_k各能级粒子数和3s_2和2p_k间粒子数反转的径向分布,研究了此分布勺放电电流、632.8nm激光辐射强度间的关系,推算了在放电管中心3s_2和2p_k能级间受激辐射的激光增益。

| Abstract: | The emission spectra from 3s_2 and 2p_k (k=1,......, 8, 10) energy levels of neon in a He-Ne laser were investigated in the absence and presence of the 632.8nm laser oscillating with a OMA-3. After Abel inversion, the radial distributions of population of 3s_2 and 2p_k, and population inversions between 3s_2 and 2p_k were obtained. The relations between the radial distributions and discharge current, 632.8nm laser intensities were studied. The laser gains of 3s_2 to 2p_k induced transitions were estimated. |
