Abstract: Abstract A single-beam pump-probe method based on a dual-channel phase measurement system was adopted to measure photo-induced phase variations caused by the photorefractive effect. This study systematically studied the dependence of photorefractive birefringence on the…

Abstract: In this paper, a generation method procedure based on a reflective metasurface is proposed to generate multiple pseudo Bessel beams with accurately controllable propagation directions and high efficiency. Firstly, by adjusting the miniaturized unit cell…
