Bilen’ka O.B. Spectroscopy of the radiation-resistant nonlinear-optical
crystals. – Manuscript.

Dissertation for the defending of the Candidate (Master) degree of
Physics and Mathematics. – Speciality 01.04.10 – Physics of
Semiconductors and Insulators. – Lviv Ivan Franko State University,
Ukraine, 1999.

The dissertation is devoted to the results of the investigation of the
spectral characteristics of the radiation-resistant nonlinear borate
oxides –BaB2O4 and Li2B4O7, nonlinear-optical and girotropic crystals
Ca3(VO4)2 and nonlinear GaP crystals in conditions of the power pulsed
laser irradiation influence.

The shape of the fundamental absorption edge of Ca3(VO4)2 is explorated.
Absorption edge takes place at 395 nm???????eV???refractive coefficient
determined at 632.8 nm is 1.864. In polarized absorption spectra the
band at 453 nm (2.737 eV; 2p(0)3dx2-y2(V)-transition and band at 541 nm
(2.292 eV; 2p(0)3dyz, xz(V)-transition) were observed. The mid-intensity
bands at 3.13 nm?(0.409 eV) and 4.00 ?m (0.310 eV) and group of the
narrow bands at 3.425 ?m (0.362 eV), 3.448 ?m (0.360 eV), 3.509 ?m
(0.353 eV) and 4.525 ?m (0.274 eV) were find.

The temperature dependence of Ca3(VO4)2 opticity dispersion (77295 K) in
the 380700 nm range was investigated. For indicated temperatures the
band gap energy was defined with help of the temperature coefficient .
The girotropy is conditioned by weak distortion of the anionic regular
tetrahedrons wmetafile8? ??U????????????

?MathType??`????uath??????The influence of power laser pulse upon
behaviour of linear electrooptical coefficient r41 in GaP for various
exciting wave-lengths is researched. The cause of changes in the crystal
by laser irradiation is an ionization of the centers with origination of
electron-hole plasma. When rising of laser irradiations’ power the most
changes of the r41 coefficient takes place at approximatly 3.39 m. This
fact has been explained by delocalization of deep levels in the crystal.
Temperature dependences of r41 are evidence of the appearance of
many-phonon processes.

Absorption and reflection spectra of Li2B4O7 and –BaB2O4 are
investigated. Lithium tetraborate crystal has an advantage compared with
beta-barium metaborate by transparency parameters in 2.53.5 m region.
Calculation of the spectral absorption coefficient in the
long-wavelength edge of fundamental absorption band allowed to determine
with help of the extrapolation of h to =0 that Eg(Li2B4O7)=6.93 eV at
T=290 K. Owing to polarized reflection data the optical functions’
dispersion (1,2()) were calculated. The band at 6.8-9.2 eV is due to
transitions between [BO4] and [BO3]-states, which formed the top of the
valence zone and bottom of conductive zone respectivly. The bands at
9.6, 10.7 and 11.9 eV are responsible for joining of the lower region of
valence zone originated from [BO3]-states and higher conductive zone
states, formed by [BO4] and [LiO4]-states. Frame oxygen s-states are
responsible for series of bands at 9.8-12.5 eV. Refractive index of
Li2B4O7 (?=632.8 nm, T=290 K) is 1.5796.

The minimum level of the Nd-laser single power pulse intensity for
–BaB2O4 and Li2B4O7, below which a crystal destruction isn’t originated
in spite of enormous number of pulses, was determined. Average within a
pulse temperatures for –BaB2O4 (422.89 K) and Li2B4O7 (462.67 K) are
determined using the many-pulsed laser destruction theory. Dependence of
surface destroy threshold of explored crystals versus surface
unhomogeneities sizes in the presence of power pulsed Nd-laser
irradiation was find. Optical parameters of the purity of crystal
surface has been estimated. They essentially reflectes on the optical
stability. Elaborated ellipsometrical diagnostics allow to define the
changes of optical properties in –BaB2O4, Li2B4O7, Ca3(VO4)2 and GaP
even at irradiation doses smaller than threshold dose. Possibilities of
usage of these crystals in the laser systems are estimated.

Absorption spectrum of –BaB2O4 before and after irradiation by dose of
40 MW/cm2 is investigated. The dependence of light irradiation threshold
of indicated crystals from long-wave boundary of transparency was found.
Peculiarity of the laser-caused injuries in crystal volume (–BaB2O4)
consists in destruction of crystal samples along 3m-planes. The
mechanism of pulsed laser-induced damage in the crystals may be
explained with help of explosive accumulation of defects in crystal
volume.

Key words: non-linear optical crystals, electrooptical effect, radiative
stability, many-pulsed laser destruction, ellipsometrical crystal
surfaces dianostics.
