Journal ArticleDOI
Theoretical investigation of noncollinear phase-matched parametric four-photon amplification of ultrashort light pulses in isotropic media
Alfons Penzkofer,H. Lehmeier +1 more
TL;DR: In this paper, the amplification of light signals (angular frequency ωS in some isotropic media (D2O, fused silica, and Schott type SF10 glasses) by noncollinear phase-matched parametric four-photon interaction ω1+ω2→ωS+ω1 is studied theoretically.
Journal ArticleDOI
Effects of order on nonlinear optical processes in organic molecular materials
TL;DR: In this paper, a general framework relating nonlinear optical processes to the molecular orientational order within the material is established, which is described as an ensemble average of orthogonal functions transforming from the molecular to the macroscopic frames using a distribution function appropriate for the particular material class.
Journal ArticleDOI
Third harmonic generation from a monolayer film of a polydiacetylene, poly-4-BCMU
TL;DR: In this paper, a conformational transition in a polydiacetylene poly4-BCMU was observed for the first time from a monolayer film on water subphase.
Journal ArticleDOI
Czochralski and modified Bridgman-Stockbarger growth of pure, Cd2+ and Nd3+ doped benzil single crystals
TL;DR: In this paper, a second harmonic generation of pure benzil from Nd:YAG laser radiation of λ = 1.06 μm with a conversion efficiency η = I 2w /I w = 0.4% was demonstrated.
Journal ArticleDOI
Carbazole main‐chain polymers for multifunctional materials: Synthesis and characterization
TL;DR: In this paper, a series of α,ω-bis(3-formyl carbazolyl)alkane monomers have been prepared starting from carbazole and α,ϵ-dibromoalkane in two steps.
