A detailed numerical study of the quantum oscillator excitation modes under a classical impact with variable frequency is performed. An analysis of the harmonic dependence of the quantum oscillator energy showed that the oscillator has frequency intervals of parametric instability, in which the oscillation amplitudes grow exponentially. The mean energy also increases, undergoing small oscillations, which are barely noticeable in resonance, and the correlation coefficient oscillates near zero level. The probabilities of leaving the ground state and passing to the second excited state are calculated for the oscillator. The penetrability of quantum tunnel barriers of moderate depth is estimated. It is shown that the increase in the barrier penetrability upon parametric excitation at the resonant frequency may be two to three orders of magnitude higher than at a detuned frequency.

The application of blood plasma, which is transparent in the visible range and similar to blood in thermophysical properties and absorption coefficient at the selected wavelengths, made it possible to study these processes in detail using video filming. The experiments were carried out using fibers with end and radial radiation output, which are most often used in phlebological practice for EVLC. The results obtained on the vein model showed the following. (i) Heating of the venous wall is mainly due to convection and boiling of the liquid. When a radial fiber is used, additional heating may occur as a result of the direct action of laser irradiation due to the Moses effect. (ii) For laser radiation with λ = 1.94 µm, effective heat transfer begins at lower power levels as compared to λ = 1.55 µm. (iii) Heat transfer in EVLC occurs asymmetrically, predominantly upward. The exception is direct heating by laser radiation due to the Moses effect, which sometimes occurs when using a fiber with a radial output (iv) Periodic events of explosive boiling help to clean the radiation output area from adhered coagulate particles, which cause undesirable carbonization.
