A solvatochromic method for determining second-order polarizabilities of organic molecules
M. S. Paley,J. M. Harris,Herbert Looser,J. C. Baumert,Gary C. Bjorklund,Dieter H. Jundt,Robert J. Twieg +6 more
TL;DR: In this paper, a simple experimental method for determining optical second-order polarizabilities of organic molecules for second harmonic generation (SHG) is developed by using a two-level quantum mechanical model.

Temperature dependence of the third‐order nonlinear optical susceptibilities in polysilanes and polygermanes
J. C. Baumert,Gary C. Bjorklund,Dieter H. Jundt,M. Jurich,Herbert Looser,R. D. Miller,John F. Rabolt,R. Sooriyakumaran,Jerome D. Swalen,Robert J. Twieg +9 more
TL;DR: In this article, the authors used optical third-harmonic generation to measure third-order nonlinear susceptibilities for thin films of planar zigzag polysilanes and polygermanes.

Compact multipass optical cell for laser spectroscopy
TL;DR: A multipass cell (MPC) design for laser absorption spectroscopy that allows for flexible path-length adjustments by simply changing the aiming angle of the laser beam at the entrance window.

Second-harmonic generation in poled organic monomeric glasses
Manfred Eich,Herbert Looser,Do Y. Yoon,Robert J. Twieg,Gary C. Bjorklund,Jean-Claude Baumert +5 more
TL;DR: In this article, second-order nonlinear optical films are prepared from glasses of two organic compounds, (S)-2-N-α-(methylbenzylamino)-5-nitropyridine and 2-N-(cyclooctylamino]-5-nithroprinidine, cooled rapidly from the isotropic liquid above the melting point.

Progress in KNbO3 crystal growth
TL;DR: In this paper, a review of known methods for the growth of KNbO 3 crystals is presented, including the use of a melt composition as close as possible to the peritectic point, accelerated crucible rotation, seed orientation and refined growth parameters.
