The acoustooptic (AO) efficiency
of Cs2HgBr4, Cs2HgCl4 and Cs2CdBr4 crystals is experimentally studied.
It is shown that Cs2HgBr4 and Cs2CdBr4 crystals are quite good AO materials.
From the results for the absorption coefficients of Cs2HgBr4 and Cs2CdBr4
it follows that the latter crystals are transparent in a wide spectral
range (up to the light wavelength of 25mm).
The AO efficiency value for Cs2HgCl4 crystal reaches h=40%
at the power P=4W of electric drive signal of piezoelectric transducer
.
Key words: acoustooptic diffraction,
light absorption, Cs2BX4 crystals.
