“…Analytical approaches for the estimation of acceptance parameters based on the small-signal approximation in the general case of biaxial crystals can be found in Ref. [65,68]. We note here only, that since the angle V Z for LIS is not far from 90 the dispersive properties and in particular the spectral acceptance are not expected to be substantially modified by propagation outside the principal planes.…”

Lithium thioindate (LiInS2) is a new nonlinear chalcogenide biaxial material transparent from 0.4 to 12 µm, that has been successfully grown in large sizes and good optical quality. We report on new physical properties that are relevant for laser and nonlinear optics applications. With respect to AgGaS(e)2 ternary chalcopyrite materials, LiInS2 displays a nearly-isotropic thermal expansion behavior, a 5-times larger thermal conductivity associated with high optical damage thresholds, and an extremely low intensity-dependent absorption allowing direct high-power downconversion from the near-IR to the deep mid-IR. Continuous-wave difference-frequency generation (5-11 µm) of Ti:sapphire laser sources is reported for the first time.

“…Both type-I and type-II phase-matching can be employed although the analysis is substantially more complicated than in the case of uniaxial crystals. It can, however, be simplified for the phase-matching in the principal planes of the index ellipsoid [21][22][23].…”

“…Several authors have since corrected and applied Ito's formulation to KTiOPO4 (KTP) [4,5] and Li830s (LBO) [5,6]. Recently, Yao, Sheng, and Shi [7] have further improved the accuracy of Ito's formulation by taking into consideration the possible difference between the polarization directions of the incident beams and the principal axes of the crystal. Phase matching via optical activity (OA) was first proposed by Rabin and Bey [8,9] and first applied by Patel and Van Tran [10] to obtain far-infrared ( -100 pm) radiation by DFM in n-InSb.…”

Phase-matching techniques and frequency-conversion efficiency in optically active crystals

Many materials of potential interest for nonlinear optical applications exhibit optical activity and this is generally not taken into account in the standard theoretical treatments of nonlinear optical effects. In this paper we examine the conditions under which optical activity significantly alters the nonlinear optical properties of a material and show how this mechanism might be used in designing a nonlinear optical device. First, an algorithm is developed to calculate the exact optimum phase-matching angles and conversion efficiency for three-wave interactions in optically active biaxial crystals. Corrections to the standard theoretical expressions for birefringent phase-matching angles and conversion efficiency are obtained for application to biaxial crystals with large natural birefringence. Second, a generalized quasiphase-matching scheme based on the presence of optical activity is formulated for three-wave interactions in second-order nonlinear crystals. It is shown that quasi-phase-matching via optical activity can be achieved by way of an effective harmonic modulation of d,z, the effective second-order nonlinear coefficient. For both these effects, it is found that optical activity makes a negligible change in the nonlinear optical properties of a material such as KTiOPO&, but they may become important for liquid crystals or polymers with high optical rotation and small birefringence.PACS number(s}: 42.65.Ky
