angles. The Gaussian behavior is formed by multiple small- angle scatters with the central-limit theorem in statistics, while the 1/θ 4 tail reflects single large-angle scattering. In cases of accelerated particles, either whole or subset of them are often modeled as a Gaussian beam becaus...
The beam propagates as a Gaussian beam at moderate and large distances from the mesh coupler. The maximum output power of the laser is of the order of 100 mW, representing the highest output power per unit volume so far reported for a continuous HCN laser. 展开 ...
aAntenna Accessories 天线辅助部件[translate] aMost of beam power focuses at the bottom of cavity as power has Gaussian distribution. This is the reason for high temperature at cavity bottom. 大多射线力量焦点在洞底部作为力量有高斯发行。 这是高温度的原因在洞底部。[translate]...
As a numerical example, the propagation properties of a hollow Gaussian beam with the power-exponent-phase vortex are demonstrated in free space. The evolutions of the normalized intensity, the phase and the orbital angular momentum density distributions are investigated, respectively. The influences ...

High diffractive efficiency (>70%) can be achieved through the transformation of the Gaussian laser beam into several kinds of two-dimensional arrays in focal plan. The application of the binary-phase gratings in the laser surface modification of ductile iron is investigated, and the results show...
Using diodenlaser pumping, we have recently demonstrated operation of such lasers,nwhich for the first time generate high (watt-level) power and a circularnGaussian beam directly from a semiconductor laser. These OPS-VECSELsnhave a strain-compensated multi-quantum-well InGaAs-GaAsP-GaAs structure...
receive rate respectively, while in our paper, we proposed a selection policy to facilitate the simultaneous eavesdropping and jamming for UAVL on the flight, which allocated the jamming power over the fading channel according to the limited jamming power constraint as well as the position of U...
In order to achieve high-efficiency OWPT systems, a monochromatic and stable light source (adapted to the receiver band gap) and beam control (optics) are needed (Figure 1). A typical configuration can be made of a light source with a large spot (typically a light bulb or an LED) focus...
