一道英文的物理题When a proton captures an electron,a photon with anenergy of 13.6 eV is emitted.What is the frequency of thisphoton?Does it lie in,above,or below the visible range?答案 当一个质子捕获一个电子时,会发射出一个具有13.6电子伏能量的光子,请问这个光子的频率是多少?它是否在可见光...
a beam of light intensity, the frequency of light through a nonlinear medium, the medium of two-photon energy is equal to the energy gap, the media will absorb two photons, a phenomenon known as two-photon absorption [4]. Figure 6.8 shows the schematic diagram of two-photon resonance abso...
The photodiodes exhibit different response speeds, and the net current at different frequencies depends on the sum of the two reverse current values. Owing to the vertical ‘V’-shaped potential distribution of the perovskite, a frequency-selective photoresponse ranging from 0.8 to 9.7 MHz (the ...
In the present experiment the 5S-5D two-photon transitions in 85Rb and 87Rb atoms as a result ofthe interaction of the femtosecond frequency comb with atomic levels of both rubidium isotopes areinvestigated. The main problem in studying of two-photon transitions is in optimization of the excitat...
We conclude that terahertz emission requires a threshold number of junctions N ~ 100. The threshold behavior is not present in the classical description of stacked Josephson junctions and suggests importance of laser-like cascade amplification of the photon number in the cavity....
The proposed generator allows the injected optical signal with arbitrary intensity modulation format. The key features of the approach are the multi-carrier frequencies generation ability and the bandwidth multiplying operation. The proposed approach is verified by simulation. Dual-chirp signal with four-...
Progress towards optical frequency standards based on two-photon transitions in atomic silver We report advances towards the development of frequency standards based on narrow two-photon transitions in the silver atom at 576 and 661 nm from the grou... MD Plimmer,T Badr,S Guerandel,... - Pro...
dependence of the two-photon absorption of neodymium laser radiation in an alcohol solution of rhodamine 6G on the intensity of the excitation field under the following conditions: single-frequency emission, emission of 3-5 axial modes, and emission of a large number of longitudinal modes (~300)...
The Cyclotron Frequency refers to the frequency of revolution of charged particles in a cyclotron, which remains constant regardless of the radius or speed of the orbit. It is a fundamental concept used in the operation of a cyclotron particle accelerator. ...
