Single-slit diffraction of the arbitrary vector beams ... polarization singularity on the diffraction fringes is analyzed. The experimental results which agree well with the simulation results show that the total intensity of the diffraction field is related only to the topological charge m, but the polarization
Electromagnetic radiation from laser wakefields in underdense pl... ... is closely associated with the structure of the laser wakefield. In general, electromagnetic radiation in the terahertz range with its frequency a few times the electron plasma frequency can be generated in the moderate intensity regime. In the high
Kilowatt high average power narrow-linewidth nanosecond all-fibe... ... was generated by modulating a continuous-wave (CW) single-frequency fiber laser at 1064 nm by using an electro-optic intensity modulator (EOIM). After multi-stage cascaded power amplification, the average power was boosted to be kilowatt level. The pulses ...
Rotation function development of four-core fiber optic tweezers ... the end face of a four-core fiber into a truncated pyramid that is asymmetric to fiber cores. Optical intensity propagation and distribution are modeled numerically, and rotation function is developed by means of calculating three-dimensional trapping ...
Simulation on terahertz emission from air plasma induced by circ... ... generated, whereas a circularly polarized carrier-envelope phase (CEP) stabilized few-cycle laser pulse is applied. Its ellipticity and intensity depend on the pulse duration of the driving laser pulse. And the polarization rotates along the CEP of the ...
Effects of acid anions, major metallic elements, and chlorides o... ... in Li-containing samples. To better use DFWM technique to analyze trace Li in actual samples, we study their effects on Li DFWM signal intensity. It is found that K, Cs, and Ni can enhance the Li DFWM signal, SO2-4..., PO3-4..., Cl-, and Ca can cause ...
Single-polarization distributed feedback fiber laser with multip... ... design with two phase shifts. No obvious differences in laser performance, including pump threshold, slope efficiency, relative intensity noise, spectral linewidth, and polarization state, are observed for the presented distributed feedback fiber laser ...
Analysis of the maximum extractable power of photonic crystal fi... ... extractable power of ytterbium-doped photonic crystal fibers. Numerically, when the diameter of core is 76-\mu m and the pumping intensity is 0.21 W/(\mu m2×Sr), the output of pure silica and ytterbium-doped photonic crystal fiber lasers is 100-kW, ...
Ultranarrow bandwidth tunable atomic filter via quantum interfer... ... bandwidth atomic filter by optically induced polarization rotation in multilevel electromagnetically induced transparency systems in hot Rb vapor. With a coupling intensity of 2.3 W/cm2, the filter shows a peak transmission of 33.2% and a bandwidth of 10 ...
Toward one nanometer X-ray focusing: a complex refractive lens d... ... a lateral size of 0.92 nm (full-width at half-maximum (FWHM)) and an axial size of 98 nm (FWHM) with intensity gain of 49050. This complex refractive lens is comprised of a series of kinoform lenses, whose aperture is gradually matched to the converging ...
