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.
