High-peak-power diode-pumped Nd:YAG laser with a Brillouin phase-conjugation--pulse-compression mirror

We demonstrate stimulated Brillouin scattering compression of diode-pumped Nd:YAG laser pulses with a 3-ns duration into 350-ps pulses at a pulse-repetition rate of 100 Hz for what is believed to be the first time. The output pulse energy was 6.5 mJ, with a beam-quality factor M(2) of 1.15, and after final amplification the energy reached 36 mJ, with M(2) of 2.5.

Transformation of the spectrum of TM polaritons of a 1D magnetic photonic crystal under conditions of the quadratic electro-optic effect

Conditions under which quadratic magneto-optical interaction leads to a number of features in the conditions of localization and propagation of collective magnetic TM polaritons are determined by the example of a 1D magnetic superlattice of the easy-axis-antiferromagnet-nonmagnetic-insulator type, in which the easy magnetization axis is orthogonal to the applied external dc electric field.     

Refraction of <Emphasis Type="Italic">s</Emphasis>- and <Emphasis Type="Italic">p</Emphasis>-polarized electromagnetic waves at the interface between a nonmagnetic insulator and an easy-axis centroantisymmetric antiferromagnet

Using the example of an easy-axis antiferromagnet with a magnetic structure of 4 _z ⁻2 _x ⁺ I ⁻ the effect of antisymmetric magnetoelectric interaction on the nature of the refraction of the bulk s- or p-polarized electromagnetic waves, incident from outside at any angle to the surface of the magnet, is studied analytically. The easy magnetic axis is collinear to the normal to the medium interface.     

The defects and spectral properties of sapphire grown by melting methods

The paper is devoted to the study of the spectral properties of the sapphire single crystals grown by Verneuil, Czochralski, Cyropulos, Stepanov and horizontal directed crystallization methods. Varing the methods, parameters of growth and starting material purity, one can control the concentration of electronic and hole centers in wide range and spectral properties of sapphire up to the irradiation.
