摘要
实验研究了目前使用的Ｎ２１２２和Ｎ３１２２掺钕磷酸盐玻璃中不同的ＯＨ基浓度对玻璃荧光寿命的影响，同时从实验和理论上研究了荧光寿命和损耗对激光增益特性的影响，结果表明：增加玻璃的荧光寿命是提高增益性能的一个重要方法，当玻璃的荧光寿命增加１０％时小信号增益系数提高５％左右。提高钕玻璃的荧光寿命，可适当降低对损耗的要求，也能够保持它的增益性能不变。
The relationship between fluorescence lifetime and OH groups concentrations in the N 2122 and N 3122 phosphate laser glass used in the Shenguan Facility is investigated experimentally. We also study experimentally and theoretically the influence of fluorescence lifetime and loss on gain property in phosphate glass. It is shown that to increase fluorescence lifetime of glass can effectively improve the gain property. When fluorescence lifetime of glass adds 10 percent, its gain coefficient will increase 5 percent. We also measured the gain of two groups glasses (4 samples) with different fluorescence lifetime and loss under the same pump condition. The results indicate that in case of keeping the gain property unchanged, we can increase its fluorescence lifetime and reduce its loss requirement.
