Аннотация:The piezoelectric coefficients and second-order nonlinear optical responses of different PbGe4O9 polymorphs were measured as a function of temperature. The PbGe4O9 crystals were found to possess attractive piezoelectric and nonlinear optical properties. The room-temperature piezoelectric charge coefficient d(11) of gamma-PbGe4O9 crystals exceeds that of quartz by a factor of 8.6. gamma-PbGe4O9 exhibits 90degrees phase matching for the fundamental frequency and second harmonic of Nd:YAG lasers.
