The peak output power for different resonant frequencies of the TE01δ mode, measured on illuminating the pentacene:p-terphenyl crystal within the strontium titanate resonator with a xenon flash lamp. The microwave power was coupled into an low-noise amplifier and detector and measured using a digital storage oscilloscope. The maximum peak power was observed at 1.4493 GHz.
