    "abstract": "We present a simple method for measuring the gain decay time in a conjugated\npolymer film by optically exciting the film with two mutually delayed\nultrashort pump pulses. When the pump is set at such a power level that\namplified spontaneous emission marginally develops along the polymer waveguide,\nthe total output emitted from its edge decays exponentially as a function of\nthe interpulse delay. The corresponding decay time represents the decay time of\nthe gain of the polymer material.",
