Abstract

We propose new transition metal (TM)-doped ZnSe/As₂S₃:As₂Se₃ composite materials for mid-IR fiber lasers. The composites are the suspension of crystalline micro- and nanosized TM²⁺:ZnSe or TM²⁺:ZnS powders in chalcogenide glasses with the refraction index matching. Mid-IR room-temperature lasing of Cr²⁺:ZnSe/As₂S₃:As₂Se₃ microcomposite material is demonstrated at the 2.4 μm wavelength.

摘要

我们提出了一种新型的过渡金属（TM）掺杂的 ZnSe/As₂S₃:As₂Se₃ 复合材料，用于中红外光纤激光器。这些复合材料是由与硫属化物玻璃折射率匹配的晶态微纳米尺寸的 TM²⁺:ZnSe 或 TM²⁺:ZnS 粉末悬浮液组成的。在室温下，Cr²⁺:ZnSe/As₂S₃:As₂Se₃ 微复合材料在 2.4 μm 波长下实现了中红外激光发射。
