Аннотация: Random nonlinear photonic crystal (NPC) structures formed by as-grown domains in a non-ferroelectric strontium tetraborate (SBO) are investigated. The domain shape and orientation are similar to those in ferroelectric KTP. Nonlinear diffraction is the simplest way to detect, evaluate and characterize these structures. Reciprocal superlattice vectors spectra of NPC in SBO are very wide and enable broadband efficiency enhancement of nonlinear optical processes. Second harmonic (SH) generation of femtosecond Ti:sapphire oscillator radiation with 1.9% efficiency is obtained using nonlinear diffraction geometry. Random quasi phase matched generation at the wavelengths of fourth harmonic of Ti:sapphire laser is obtained with average power up to 1 ?W. © 2010 Copyright SPIE - The International Society for Optical Engineering.
