A new class of glasses for second-harmonic generation

Photoinduced nonlinear optical effects in the Pr doped BiB3O6 glass nanoparticles incorporated into the polymer matrices

“…Another approach [11] is based on the spatial-periodic orientation * Corresponding author. of the optical medium under influence of low-frequency light field [12].…”

Multicomponent glass materials with the raised efficiency for conversion of laser radiation frequency

“…It was observed that the lead-containing glasses have the efficiency up to two orders of magnitude higher than the pure samples [8]. More big absolute efficiency of SHG ∼10 -5 has been observed in phosphate glass with containing 38 mol.% PbO 2 and 5,5 mol.% CeO 2 [7] (see sample SHG23 in Table 1). There is an assumption, that the possible activators in glasses can be the rare-earth elements and some from groups of IV and V (Ge, Ti, P, N) [1,8].…”

“…Phosphate glasses have high beam stability and are perspective for various laser elements with a high transparency in visible and near UV areas. The basic activator for growth of the efficiency of photo-induced SHG signal in these media is the big content of lead oxides ∼40mol.% [7]. It was observed that the lead-containing glasses have the efficiency up to two orders of magnitude higher than the pure samples [8].…”
