X‐ray detectors have obtained great attention in medical diagnostics, security checks, and space exploration. However, ion migration of X‐ray detectors results in dark current drift, low signal‐to‐noise ratio, and degradation of detection performance. Here, ion migration properties of Li2ZrTeO6 and ZrTe3O8 are comprehensively investigated by theoretical analysis and experimental results. ZrTe3O8 single...
The Q‐switched material and device have attracted extensive attention due to their irreplaceable role in pulsed lasers. In this paper, BaO–TeO2–WO3 glass (BTW glass) with sound velocity and sound attenuation coefficient of 3422 m−1 s and 0.653 dB cm−1 is successfully selected and fabricated as acousto‐optic material. Both free‐spaced and fiber‐coupled acousto‐optic modulation devices based on BTW...
