摘要：The photoinduced birefringence effect in a type of azo-dye-doped poly (methyl methacrylate) was realized when it was pumped by a polarized argon ion laser beam. The transmission of a 632.8 nm probe beam through the pumped sample could be controlled by two kinds of methods: one employed the photoinduced thermal effect of the pump light in the azo-dye-containing sample, and the other changed the temperature of the sample directly. The tunable transmission of the probe light with different pump power and at various temperatures of the sample was investigated in detail.
