“…As an important II-VI semiconductor, zinc selenide (ZnSe) was one of the earliest discovered semiconductors, and is probably one of the most critical electronic and optoelectronic materials, with outstanding applications in nonlinear devices [9]. Compared with silicon and quartz, ZnSe has an excellent medium and far infrared transmittance (0.5-22 µm), a high refractive index (2.3-2.5), and a high nonlinear refractive index (8.3 × 10 −18 m 2 /W) [10,11]. ZnSe has good mechanical properties, high thermal conductivity, and is insoluble in water.…”

A rapid and single-step method for the fabrication of a zinc selenide (ZnSe) concave microlens array through the high-speed line-scanning of a femtosecond laser pulse is presented. Approximately 1.1 million microlenses, with minimized volume and high transparency at wavelengths between approximately 0.76–20 μm were fabricated within 36 min. More importantly, the size of the microlenses can be controlled by adjusting the laser power. Their high-quality infrared optical performance was also demonstrated. This method holds great promise for the development of ZnSe-based micro-optical devices.

ZnS‐reinforced ZnS/ZnSe composites are prepared by chemical vapor deposition. Scanning electron microscope, transmittance, and bending strength are used to characterize the samples. The schematic diagram of the transmittance model of the double‐layer composite window is used to calculate the theoretical transmittance, and the measured value of the transmittance of ZnS/ZnSe composite material is in good agreement with the calculated value. The effects of interface layer on the optical and mechanical properties of materials are studied in detail. It is found that the interface can affect the transmittance of the composites, but it still maintains a high transmittance, and the influence of interface layer on the transmittance of visible band is more serious than that of infrared band. Moreover, the mechanical properties of the new composite material are significantly improved (35%).
