Ｃｒ4 + ∶ＹＡＧ晶体的受激辐射在 12 5 0～ 15 80ｎｍ近红外波段 ,正是光纤通信的低损耗窗口 ,因此Ｃｒ4 + ∶ＹＡＧ激光器在光通信研究领域有应用前景。图 1实验装置图Ｆｉｇ .1Ｅｘｐｅｒｉｍｅｎｔａｌｓｅｔ ｕｐ 本实验小组用掺Ｃｒ4 + 浓度为 2 .5× 10 17/ｃｍ3 的
The stimulated emission of Cr4 +: YAG crystals in the near-infrared region of 125 ~ 1580nm is the low loss window of optical fiber communication. Therefore, the Cr4 +: YAG laser has potential applications in optical communication research.
