Investigation of trigonal (La1−xNdx)3Ga5SiO14 crystals. II. Spectral laser and electromechanical properties

Abstract

Absorption, luminescence characteristics, and stimulated emission parameters of Nd3+ ions in the wide temperature region of a full concentration series of (La1−xNdx)3Ga5SiO14 single crystals are studied. Luminescence intensity characteristics are analyzed and transition cross-section at the laser wavelengths of two 4F3/2 → 4I11/2 and 4F3/2 → 4I13/2 generation channels of activator are determined. Registered induced transitions are identified. Electromechanical characteristics of La3Ga5SiO14, specifically, elastic, dielectric, and piezoelectric modules and constants are investigated. A comparison of the properties between La3Ga5SiO14 crystals and crystalline SiO2 is carried out. [Russian Text Ignored.]
