The refractive, elastical and piezooptical properties of the lithium
tetra borate crystals have been investigated. The dispersions of the refractive
indexes of Li2B4O7 crystals have been measured in the wavelength range
350-650 nm. The results of the measurement of velocity of the longitudinal
and transverse ultrasonic waves in lithium borate crystals are presented.
On the base of ultrasonic velocity measurements the components of the elastic
matrix Cmn of these crystals have been calculated. Using the determined
values of the refractive, elastical and elastooptical tensor components
the acoustooptical quality M2 of Li2B4O7 crystals has been calculated.
Key words: borate crystals, piezooptical effect, acoustooptical effect,
sound velocity.
