Cladding Waveguides in Aminoacid Crystal: Fabrication and Second Harmonic Generation

Not Accessible

Your library or personal account may give you access

Abstract

Cladding waveguides were inscribed in L-threonine aminoacid crystals by fs-laser pulses. Guided second harmonic generation was observed at 390 nm, with an efficiency of 1.3% (MW cm2)−1. Such results open new opportunities in organic nonlinear photonics.
