Nonlinear optical properties of
BaAlBO_3F_2 crystal

open access: yesOptics Express, 2009
We investigated the nonlinear optical properties of new BaAlBO(3)F(2)(BABF) crystal. The high quality BABF is nonhygroscopic and possesses a moderate birefringence suitable for UV light generation. On the basis of its refractive index dispersion curves, it is inferred that BABF has great potential applications nonlinear optical material, notably for UV

Laser-induced damage threshold comparison of untreated, antireflection-coated and antireflection-microstructured LiGaS2 nonlinear crystals

open access: yesHigh Power Laser Science and Engineering
LiGaS2 crystals are prospective media for optical parametric oscillators. In such systems efficiency and maximum power output are often limited by the laser-induced damage threshold (LIDT) of nonlinear crystals.

Spectral behavior of second harmonic signals from organic and non-organic materials in multiphoton microscopy

open access: yesAIP Advances, 2015
Multimodal nonlinear microscopy allows imaging of highly ordered biological tissue due to spectral separation of nonlinear signals. This requires certain knowledge about the spectral distribution of the different nonlinear signals. In contrast to several
