Metamaterial absorbers have attracted more and more attention because they can achieve perfect absorption in some specific structures. At present, although most absorbers can achieve perfect absorption in one or more frequencies of the visible or nea

We present a cell-phone based polarized microscope for diagnosing malaria through hemozoin recognition over a wide FOV accompanied with decent image performance. The system is constructed based on attachment method using a lens assembly as objective,

All solid-state microchip lasers having the advantage of short cavity lengths give them tremendous potential as pulsed devices for short pulse laser generation. In this work, by constructing a compact microchip-like laser resonator, we have demonstra

We report on diode-pumped continuous-wave Pr-doped yttrium lithium fluoride (Pr:YLF) laser and its frequency doubling to 320 nm. The maximum output power of the 640 nm fundamental wave reached 3.44 W with a slope efficiency of about 48.3%. Using a ty

Though people have experimentally studied the temperature dependence of the refractive index (RI) of optical fibers made of amorphous silica (a-SiO 2 ), the temperature ranges in the previous experiments are usually below 800 K, and a rigorous theore

The signal distortions of the microwave photonic bandpass filter based on stimulated Brillouin scattering is presented in this paper for the first time. We assume that modulated signal pulse propagates through a continuous-wave-pumped Brillouin fiber

BackgroundCoexisting primary aldosteronism (PA) and subclinical Cushing's syndrome (SCS) caused by bilateral adrenocortical adenomas have occasionally been reported. Precise diagnosis and treatment of the disease pose a challenge to clinicians due to
