Abstract

Lithium triborate crystals LiB₃O₅ (LBO) considered as a high efficiency nonlinear material that is applied to transform laser beam frequency. The most effective application of the crystal is the transformation of neodymium based laser with 1064nm wavelength to the second and to the third harmonic generation. The high damage threshold and operation characteristics of LBO are the reasons to use it in wide-aperture high-power laser systems with aperture diameters up to several cm. Experimentally it was verified that improved crystal growth technique allows to grow the crystals that are given the opportunity to enlarge the dimensions of nonlinear elements by modifying the ratio of the grown crystal dimensions, i.e. habitus.
