【摘要】 我们从标准Voigt线型曲线族看出η≤1.2的曲线十分接近于η=0即均匀展宽的曲线。结合实验事实,澄清了关于使增益介质均匀展宽占优势的概念,并且详细推导了均匀展宽激光器自发产生单纵模运转的条件。更多还原

【Abstract】 It is found from the family of standard Voigt profiles that the curves of η≤　 1.2 are very close to the curve of η=0 (homogeneously broadened). Combining with the experimental facts, the concept of making the gain medium predominantly homogeneously broadened is clarified and the conditions of single- longitudinal- mode operation without special optical mode-selection for homogeneously broadened lasers are deduced in details.更多还原
