Indium Tin Oxide nanowire arrays (ITO-NWAs), as epsilon-near-zero (ENZ) materials, exhibit a fast response time and low saturable absorption intensity, which make them promising photoelectric materials. In this study, ITO-NWAs were successfully fabricated using chemical vapor deposition (CVD) method, the properties of material characterized in near-infrared region. Further, passively Q-switched all-solid-state lasers realized at wavelengths 1.0, 1.3, 2.0 µm as-prepared absorber (SA). To best...
We investigate the third-order optical nonlinearity in silicon nitride (SiN) films prepared using magnetron sputtering. The large nonlinear refractive index n2 SiN at room temperature of a value −2.00 × 10−16 m2/W and absorption coefficient β 1.44 10−9 m/W are determined by Z-scan method wavelength 1064 nm pulse duration 25 ps. is three orders magnitude larger than that chemical vapor deposition 1.55 μm. enhanced up to −6.27 slightly changed β, indicating an ratio |Reχ(3)|/|Imχ(3)|, further...
This Nd:BG1-xSxO (Nd:BGSO) crystal was grown using the micro-pulling-down method, and continuous-wave laser operation of this demonstrated for first time, to best our knowledge. The maximum output power 1.038 W obtained under absorbed pump 3.01 W, which corresponds a slope efficiency 31.3%. Bismuth nanosheets were employed as saturable absorbers generate passively Q-switched Nd:BGSO laser. Stable pulses with shortest pulse width 376.5 ns repetition rate 136.6 kHz achieved at W. largest...
