Proof of this fact is beyond the scope of this book, and the need to use quantum mechanics to explain the interaction between radiation and matter. However, the concept of induced transitions, or the interaction between signal and atomic systems, but with the classical electron oscillator model can qualitatively be explained by electromagnetic radiation, r the charge of material in the interaction with the material now to examine the bound electron by the nucleus key ideas together by elastic electron and ion can oscillate around the equilibrium position. The laser beam of 50mW green laser pointer is very stable.
Electric field between the electron and the nuclei deviate from the thermal equilibrium position of the relative displacement, they oscillate around the equilibrium position, therefore, the model shows a characteristic oscillation or resonance, and an external field increases the response. Because the quality of the nucleus is much larger than electronic, so you can supposedly only electrons in motion. To understand the interaction of light with matter is the most important model harmonic oscillator model, in this model, assuming there is an electronic effect in a linear tension was bound under its equilibrium position. You can think of this e-spring suspension with a particle is. classical electromagnetic theory is that each oscillation of the charge or dipole antenna with mini-sub, as it continued to around the radiated electromagnetic energy. Users can manipulate the receiver by clicking the related functional keys on the RF remote of green laser pointer with remote control.
On the electric dipole transition and the classical electron oscillator model in detail, please refer to the literature [1.3] This section will discuss the dominant material in the process of absorption and amplification of the quantitative relationship. This requires the introduction of the concept of atomic linear, so that the mathematical model more realistic 'Therefore, the first study led to an important feature of the different atoms and linear physical processes, in the derivation of Einstein coefficients, have assumed a frequency of,:; of monochromatic waves has infinite energy levels in the narrow role of h,: the two-level systems now have to consider is, with limited transition width △, the atomic system with a bandwidth of d, the interaction between signals. In order to obtain the transition rate under these conditions the expression, atoms must be introduced the concept of linear function g (,,,。). To, O is the center of the distribution g (., Years old.) Is the spectral line broadening the balance of linear transition, set N: for the study had previously been on the level of plasma total, the unit of frequency distribution of the ion spectrum. Some 100mW green laser pointer have the function of black screen.
If all points on both sides of the frequency, the function was known to the state if,,. ), You can find the level 1, one (old Feng d,) within the frequency range of the absorption of atoms N (,) d,, or level 2 in the same frequency range emitted atoms, according to type (1,21), was based on the foregoing, can be classes, and dynamic frequency is defined as the unit interval the probability of photon emission or absorption, sog (port) d, leading to energy h. An h (, + d,) between the photon emission (or absorption) of a particular transition probability in, 20, and the second transition occurs between the two probabilities must be 1. Where, N: as level 2 atomic number, Diao NZ / nine in a (, + d,) between the spontaneous emission of photons per second, the number of atomic transitions and line width depends on the line broadening. In gas, the optical frequency transitions for level lifetime, collisions, Doppler broadening and other factors and widened.
