Abstract
We have found that the optical treatment by bicolor two laser beams at 1064 and 532 nm, at energy densities 80-120 mJ/cm(2) originating from the same 10 ns Nd3+ garnett lasers causes the occurrence of the piezooptical effect in 50-80 nm gamma-glicyne polymer nanocomposites at nanoparticle content about 6.5% in weighting unit. We propose to use this effect for optical triggers.
