摘要：

Glass waveguiding films were prepared from titania and modified silica using the sol-gel method and doped by the laser dye rhodamine B. The guided and amplified fluorescence (pumped by a double frequency Nd-YAG laser) was coupled out either by static grating written on the film or by a prism. The gain of the emitted superradiance was determined from the amplified spontaneous emission intensity dependence on the pumped strip length. A maximum net gain of 54 dB/cm was measured.© 1995 American Institute of Physics.
