提出了一种基于铯原子拉曼跃迁的坏腔拉曼激光器,并分析了表示集体效应的自旋相关系数,光子通过禁戒跃迁以集体方式发射并耦合进入低Q谐振腔,功率可达10-9W量级。计算了该激光器的一些工作参数和特性,如抽运阈值、输出功率随各种条件的变化趋势,研究结果对今后的研究和实验有所帮助。 A kind of bad cavity Raman laser based on the Raman transition of cesium atoms is proposed and the spin correlation coefficient which represents the collective effect is analyzed. The photons emit in collective mode and couple into the low Q cavity through the forbidden transition. The power can reach 10 -9W magnitude. Some operating parameters and characteristics of the laser, such as the pumping threshold and output power, have been calculated. The research results are helpful for the future research and experiment.
