Acoustooptic and acoustic properties of KLiB4O7 crystals

Abstract

The acoustic and acoustooptic (AO) properties of KLiB 4 O 7 crystals are experimentally studied and analysed. It is shown that the above crystals can be used as a material for AO applications. The AO figure of merit calculated for the slowest acoustic wave is equal to M 2 =(332±120)×10 -15 s 3 /kg. Propagation of the acoustic energy flow in KLiB 4 O 7 for the cases of transverse and longitudinal acoustic waves is considered. It is shown that the obliquity for the slowest transverse wave is relatively small and so it cannot affect essentially the efficiency of AO interaction.

Kerr and Faraday effects in borate glasses

“…They are widely used in parametric optical oscillators as functional elements [13,14]. Recently we have shown that the borate crystals may also be used as acoustooptic materials, in particular for acoustooptic operation of laser radiation in the short-wavelength spectral range [15][16][17][18][19][20][21][22][23]. We should also notice that the acoustooptic interactions do not require a lack of centre of symmetry, being possible even in the isotropic glasses.…”
