Investigation of nonlinear optical properties in α-A₂BB′O₆ (A = Li, Na, K; B = Ti, Zr, Hf; B′ = Se, Te) by first-principles calculations

Abstract

Nonlinear optical (NLO) crystals based on oxides typically have wide bandgaps and large laser damage thresholds (LDTs), which are important for generating high-power and continuous terahertz radiation. Recently, a new...
