Linear and Nonlinear Holographic Gratings in Saffron
S. Ahmadi Kandjani, S.W. Chan, R. Barille, S. Dabos-Seignon and J.-M. Nunzi

Holographic recording and second harmonic generation by means of optical poling were achieved in saffron as a cheap and biodegradable material. Characteristics of the light-induced birefringence, volume gratings and all optical poling dynamics are studied.
