“…A wide range of their optical transparency, particularly in the ultraviolet (UV) spectral region [7][8][9][10][11] (up to 125 nm for 4 7 SrB O [10, 11]), and a high level of optical damage threshold [11,12] make them one of the best materials for operation of short-wavelength high-power laser radiation. As shown in the works [13][14][15][16][17][18][19][20], some of the borate crystals also manifest high enough acoustooptic figure of merit (abbreviated hereafter as AOFM).…”

Highly efficient acoustooptic diffraction in alpha-BaB2O4 crystals: improving of geometry of acoustooptic interaction

Abstract.In the present work we show experimentally on the example of -BaB 2 O 4 crystals that a choice of the slowest acoustic wave for acoustooptic interaction made on the basis of acoustic anisotropy of crystals can essentially increase the acoustooptic figure of merit. The latter parameter for -BaB 2 O 4 obtained by us is equal to M 2 =(211±31)10 -15 s 3 /kg. We demonstrate that the acoustooptic diffraction efficiency in -BaB 2 O 4 increases for shorter wavelengths of optical radiation and reaches almost ~ 75% at the wavelength 325 nm (at the acoustic signal power 0.04 W). This fact, along with transparency of those crystals in the ultraviolet spectral range and their high resistance against a powerful laser radiation, make them attractive materials for operating high-power ultraviolet laser radiation.

“…It is known that anhydrous borate crystals are resistive to powerful optical radiation and manifest a wide range of optical transparency, extending from the vacuum ultraviolet as far as to the infrared spectral region [1][2][3][4][5]. Non-centrosymmetric representatives of this family are efficient nonlinear optical materials [2,5,[6][7][8][9][10][11] and also manifest high optical resistance [12].…”

Electrooptic Kerr and magnetooptic Faraday effects are studied in LiKB 4 O 7 , Li 2 B 6 O 10 and LiCsB 6 O 10 glasses. The corresponding quantitative coefficients are determined for the wavelength of 632.8 nm. It is shown that the above compounds can be used as electrooptic and magnetooptic materials which are highly resistant to powerful optical radiation and transparent in the ultraviolet spectral range.
