Low-cost dual-comb spectrometer for CO2 monitoring based on gain-switched semiconductor lasers Results Phys. (IF 5.3) Pub Date : 2024-02-27 L. Monroy, C. Quevedo-Galán, A. Pérez-Serrano, J.M.G. Tijero, I. Esquivias
Dual-comb spectroscopy (DCS) is an emerging technique that has attracted the attention of the research community due to its fast data acquisition and high-spectral resolution properties. Despite its versatility and mechanical stability, the complexity and cost of high performance DCS are still experimentally challenging. We propose a simple and compact DCS system that significantly reduces system costs

Properties of an elegant Laguerre-Gaussian beam in the receiver plane of Airy transformation Results Phys. (IF 5.3) Pub Date : 2024-02-27 Yong-Zhou Ni, Jian He, Jia-Hao Chen, Fei Wang, Yi-Min Zhou, Guo-Quan Zhou
As the superposition of an even and odd modes constitutes an elegant Laguerre-Gaussian beam (ELGB), Airy transformation of the even mode, the odd mode, and the ELGB is studied. Analytical expressions of the even mode, the odd mode, and the ELGB in the receiver plane of Airy transformation are derived, respectively. Also, the analytical centroid and the analytical beam width for the arbitrary even mode

Achieving shot noise limit imaging with a polarization-modulated optical loop in a laser frequency-shifted feedback system Results Phys. (IF 5.3) Pub Date : 2024-02-26 Borui Zhou, Bing Zhou, Jianling Yin, Yue Cheng, Qi Chen, Xueju Shen
This paper introduces a novel approach to attain the shot-noise limit in laser frequency-shift feedback (LFSF) imaging systems by employing a polarization-modulated optical loop. Compared to the traditional LFSF imaging system, the proposed system effectively eliminates detrimental parasitic feedback signals, enhancing both the signal-to-noise ratio and the response range of the LFSF imaging system
