    Highly sensitive and real-simultaneous CH4/C2H2 dual-gas LITES sensor based on Lissajous pattern multi-pass cell by Haiyue Sun, Ying He, Shunda Qiao, Yahui Liu, Yufei Ma

    Published 2024-11-01
    “…Two kinds of fiber amplifier, erbium doped fiber amplifier (EDFA) and Raman fiber amplifier (RFA), were combined to amplify the output power of two diode lasers to improve the excitation strength. After optimization, minimum detection limit (MDL) of 268.8 ppb and 91.4 ppb for real-simultaneous CH4 and C2H2 sensing were obtained, respectively. …”

    Size Effects on Surface Elastic Waves in a Semi-Infinite Medium with Atomic Defect Generation by F. Mirzade

    Published 2013-01-01
    “…The paper investigates small-scale effects on the Rayleigh-type surface wave propagation in an isotopic elastic half-space upon laser irradiation. Based on Eringen’s theory of nonlocal continuum mechanics, the basic equations of wave motion and laser-induced atomic defect dynamics are derived. …”
