Description	U monoklinálních krystalů byly měřeny elektronické a optické vlastnosti. La2CaB10O19 (LCB). (cs) The electronic and optical properties have been calculated for monoclinic La2CaB10O19 (LCB) crystal using the state-of-the-art full potential linear augmented plane wave method. We present results for the band structure, density of states, birefringence, imaginary and real parts of the frequency dependent linear and nonlinear optical response. We have found that LCB is a semiconductor with an indirect energy band gap of about 4.45 eV. A simple scissor operator is applied to adjust the band energy gap from the calculations to match the experimental value (5.4 eV). The calculated birefringence of the LCB crystal has positive sign in agreement with the experimental data. Calculations are reported for the frequency-dependent complex second-order nonlinear optical susceptibilities chi((2))(abc)(omega) up to 6 eV and for zero-frequency limit chi(2)(0). LCB exhibits second harmonic generation efficiency about two times larger than KDP crystal (KH2PO4).
