Influence of PbO concentration on photoinduced second-harmonic generation in lead glasses

摘要

We report experimental studies of photoinduced second-harmonic generation (SHG) in lead glasses with different PbO concentrations. The dependencies of photoinduced second-harmonic saturation efficiency on PbO concentration and calculated third- order nonlinearity are observed. The optical concentration of PbO for photoinduced SHG is found to be approximately 50 wt%. Experimental results are interpreted on the base of photovoltaic model.
