Adamiv V.T. Optical and physical properties of BaB2O4 single crystals
grown in (- and (-phases. — Manuscript.

Thesis for Candidate of Science Degree in Physics and Mathematics by
speciality 01.04.05 — optics, laser physics — Institute of Physical
Optics, Ministry of Education of Ukraine, Lviv, 1999.

The dissertation is devoted to growth and complex investigations of
optical and physical properties of BaB2O4 single crystals for both
structural phases — low-temperature noncentrosymmetrical (-BaB2O4 (BBO)
and high-temperature centrosymmetrical (-BaB2O4 (ABO), devided by the
phase transition at 925(C. The growth method for these crystals
including all peculiarities of the process is studied in details.

It is shown that the choise of starting chemical agents and the
synthesis process of growth mixture are very important moments for
growth technology of optically qualitative BaB2O4 single crystals for
both modifications. The most expedient reagents for synthesis are BaCO3,
Na2CO3 and H3BO3. The synthesis of growth mixture by the method of
solid-state reaction with graded heating process is fulfilled. The
optically best BBO and ABO single crystals are obtained by the
top-seeding in the optical axis direction. Microcavities are the typical
defects for the crystals; the majority of them have internal cut and can
be interpreted as negative crystals, filled up with remains of
melt-solution.

The results of investigations of mechanical, thermal and
electrophysical properties for single crystals of both phases are
presented. The considerable anisotropy between the main
crystallophysical planes for microhardness and fragility of BBO crystals
is determined. The excessive fragility gives the possibility do
determine only the lower boundary of suitable value of microhardness for
the plane perpendicular to c-axis, which equals 2 GPa. The knowledge of
these values allows to elaborate a cutting technology and machining for
single crystal samples with high optical quality. The temperature
dependences of linear thermal expantion for BBO and ABO single crystals
in temperature region 100 — 1070 K differ essentially. For ABO crystals
the dependences (11(T) and (33(T) have almost linear character, while
for BBO crystals the dependence (33(T) has cupola-like form. The
negative values of (11 for both crystals are explained on the basis of
their pseudolayered structure and the differences in (33(T) dependences
are connected with differences in phonon spectra. With the aim of
minimization of thermal stress influence on optical parameters and in
the operation of nonlinear optical elements in correspondent devices it
is nesessary to take into account the existence of so strong anisotropy
of linear thermal expansion in BBO crystals in the process of postgrowth
cooling. The temperature dependences of electroconductivity for both
crystals in 300 — 900 K region are investigated. The conductivity
mechanism is ascertained and the small difference between (11 and (33
coefficients is determined.

The measurements of piezooptical effect in BBO crystal on the special
experimental installation, which allows to measure all piezooptical
coefficients (im without changes of the sample position by the
interferometric method are fulfilled. The coefficients of induced
birefringence ((km by polarisation-optical method are measured also. In
result for BBO the eight independent piezooptical coefficients at
constant induction and electric field and the magnitudes of
elastooptical coefficients are calculated. Rather high values of
elastooptical coefficients in BBO together with small density and sound
velocity of transversal waves ensure its high acoustooptical quality (I2
( 129.0(10-18 s3/g). High radiational stability of BBO single crystals
(the optical damage threshold ~4 GW/cm2 at (=1.079 (m) and good
acoustooptical characteristics allow to suggest these crystals for
designing of acoustooptical modulators for powerful laser beams.

The comparative investigations of luminescent properties of BBO and ABO
single crystals which were grown from the same chemical agents are
fulfilled. The conclusion about possible prospects for use of ABO
detectors of ionised radiation is made over results of investigations,
because the ligh efficiency of X-ray luminescence is high in comparison
with known crystals.

The pyroelectric scintillation in (-BaB2O4 crystals in 77-400 K
temperature region, which shows the appearance of strong electric fields
and electric discharges on the crystal surface, is ascertained.

m symmetry phase — ferroelastics, moreover the parent phase possesses
m3m symmetry.

Key words: barium borate, single crystal, piezooptics, acoustooptics,
