Growth of high quality large size LBO crystals for high energy second harmonic generation

Observation of a different birefringence order at optical and THz frequencies in LBO crystal

“…producer as for the previous study [8], the Institute of Geology and Mineralogy SB RAS, Russia [4]. It was found that the birefringence order at THz frequencies was in agreement with that at optical frequencies -i.e.…”

“…−5 cm −1 [3,4]. It has the highest surface damage threshold for laser radiation amongst all known nonlinear crystals, which is even higher than that of UV-grade fused silica [5].…”

“…Polarizabilities can be calculated from equation (4) and are shown in Table 2. It is seen in Table 2 that the ionic polarizability component is 125 significantly lower for a wave polarized along the Z axis than for the X or Y axes.…”

“…LBO has the advantages of very high optical damage threshold, very low opti-155 cal losses in the visible, absence of multiphoton absorption, and good thermal, thermo-optical and mechanical properties [1,3,4,5,9,10], all of which make it an attractive crystal for nonlinear generation of THz radiation.…”

Dynamic control over the heat field during LBO crystal growth by High temperature solution method

“…According to this aim, our approach to modify high temperature solution method for LBO crystal growth was based on the method of heat field symmetry change and rotation [3]. We suppose that suggested approach provides the following advantages:…”
