自终止型金属蒸气激光g 判据的进一步验证

The G-criterion advanced by applicant previesly used for self-terminating transition in pulsed discharge-excited metal vapor laser has been successfully extended from neutral atomic laser medium to single ionic laser medium. It has been validated further.The lasing oscillations of self-terminating transition instrontium ions (1.03μm/1.09μm) and in calcium ions(0.85μm/0.87μm) have been achieved..A set of laser oscillations of four strontium atom spectrum lines simultaneity have been obtained for the first time, those corresponding wavelengths were 2.92μm，3.01μm，2.69μm and 2.60μm espectively, their ratios of intensity were 5:4:4:1 and total average laser power was 10mW. As far as our knowledge goes, the laser spectrum lines have been never reported except 3.01μm.On the basis of analyzing characteristics of corresponding energy levels and experiment phenomena, the action mechanism was discussed preparatory, the propose of classify into the M-M transition laser was advanced.

选择砷、锗、硅和三氯化铼为激光工作物质，氖、氦为缓冲气体，经由高压脉冲纵向放电激励，获得相应元素的自终止类型激光振荡，通过直接实验进一步证明先前提出的自终止类型金属蒸气激光器高效运转的补充判据－ｇ判据。. 完善和深化有关激光机制的认识，对探索此类激光的新谱线有指导意义。
