Amplification in a semibounded free-electron laser

A self-consistent analytic expression for the complex gain of a free-electron laser is obtained on the basis of the single-particle equations with realistic boundary conditions. The results are presented in the form of amplitude-frequency and phase-frequency characteristics of a free-electron laser.New-Accelerator Problems Laboratory, Lebedev Physics Institute, Academy of Sciences of the USSR.

Coherent interaction of an electromagnetic field with a medium of two-level particles and with a superconducting current in a Josephson structure

The propagation of electromagnetic pulses in Josephson structures is investigated theoretically. An analogy with interaction of light pulses with a twolevel medium is traced. Under certain conditions the propagation of electromagnetic radiation in a two-level medium and in a Josephson structure is described by the same wave equation.Lebedev Physics Institute, Academy of Sciences of the USSR, Moscwow.

Anomalous mass transfer and phase and structural changes in α-Fe when acted upon with electron pulses

The phase composition and the defect structure of armco-iron irradiated with a relativistic electron beam is investigated using electron microscopy and x-ray structural analysis. Specimens with a chromium coating and without it were irradiated.Tomsk State University Architecture-Building Academy.

Coherent effects in two-level amplifying and SRS-active media

Some results are reported on coherent propagation of optical pulses. In particular, a solution is presented of the Maxwell-Bloch equations for the case of amplification of high-power pulses with varying carrier frequency but with constant number of photons in the pulse.Lebedev Physics Institute, Academy of Sciences of the USSR, Moscow.

Vertical rotation effect on turbulence characteristics in an open channel flow

This paper solves the three-dimensional Navier-Stokes equation by a fractional-step method with the Reynolds number Reτ=194 and the rotation number Nτ=0-0.12. When Nτ is less than 0.06, the turbulence statistics relevant to the spanwise velocity fluctuation are enhanced, but other statistics are suppressed. When Nτ is larger than 0.06, all the turbulence statistics decrease significantly. Reynolds stress budgets elucidate that turbulence kinetic energy in the vertical direction is transferred into the streamwise and spanwise directions. The flow structures exhibit that the bursting processes near the bottom wall are ejected toward the free surface. Evident change of near-surface streak structures of the velocity fluctuations are revealed.     

Fueling Peter’s Mill: Mikhail Lomonosov’s Educational Training in Russia and Germany, 1731–1741

This article, the second in a series about the Russian scientist Mikhail Lomonosov (1711–1765), traces his education from his arrival in Moscow in 1731 to study at the Slavic-Greco-Latin Academy, through his admission to the St. Petersburg Academy of Sciences in 1736, to his trip abroad to complete his educational studies from 1736 to 1741. Lomonosov’s story during this time opens a vista on the introduction of modern physics and modern science into Russia. Michael D. Gordin has argued that Peter the Great’s plans to Westernize Russia were more broadly conceived than he is usually credited, with ambitions that exceeded mere utilitarian and pragmatic goals. Lomonosov’s career trajectory is a good example, illustrating how different aspects of the Petrine vision intersected with and reinforced each other. The article ends with Lomonosov’s return to Russia from Germany in 1741, an important landmark in the growth of the Academy and of Russian science.     

System for nanosecond and picosecond laser synchronization using high-voltage semiconductor switches

Results are presented on the development and investigation of a system for the synchronization of the emission of a nanosecond laser, used for plasma heating, with the emission of a diagnostic picosecond laser. The system is based on the use of the fast-semiconductor-switch technology, and ensures a temporal synchronization instability not higher than 100 psec.Laser-Plansma Laboratory and Special Design Office.

Generalized Bethe ansatz equations for Hofstadter problem

The problem of diagonalization of the quantum mechanical Hamiltonian, governing dynamics of an electron on a two-dimensional triangular or square lattice in external uniform magnetic field, applied perpendicularly to the lattice plane, the flux through lattice cell, divided by the elementary quantum flux, being a rational number, is reduced to the generalized Bethe ansatz like equations on the high genus algebraic curve. Our formulae for the trigonometric case, where the genus of the curve vanishes, contain as a particular case a recent result of Wiegmann and Zabrodin.Supported by the Russian Academy of Sciences and Academy of Finland     

Generalized coherent states of multimode light,and biphotons

Generalized coherent states of a multimode field are analyzed within the framework of the dynamic-symmetry approach and with allowance for polarization. A new class of unpolarized two-photon states is defined. The uncertainty relations and statistical and other properties of optical fields in these states are calculated and analyzed. The relations between the considered states and squeezed states of light are discussed.Optics Laboratory, Lebedev Physics Institute, Academy of Sciences of the USSR.

An investigation was made of plasma radiation spectra created by a modulated rf discharge having an anomalously low operating voltage, in krypton, xenon, argon, and neon.
