| description | Herein, we report a novel optical glass material, fluoroaluminate (AlF<sub>3</sub>) glass, with excellent optical transmittance from ultraviolet to infrared wavelength ranges, which provides more options for application in optical devices. Based on its performance, the phase-type Fresnel zone plate (FZP) by ultraviolet femtosecond (fs) laser-inscribed lithography is achieved, which induces the refractive index change by fs-laser tailoring. The realization of ultraviolet fs-laser fabrication inside glass can benefit from the excellent optical performance of the AlF<sub>3</sub> glass. Compared with traditional surface-etching micro-optical elements, the phase-type FZP based on AlF<sub>3</sub> glass exhibits a clear and well-defined geometry and presents perfect environmental suitability without surface roughness problems. Additionally, optical focusing and multi-wavelength imaging can be easily obtained. Phase-type FZP embedded in AlF<sub>3</sub> glass has great potential applications in the imaging and focusing in glass-integrated photonics, especially for the ultraviolet wavelength range. |
