Abstract
The possibility of creating free electron lasers without inversion (FELWI) is shown to have threshold character with respect to the intensity of wave to be amplified. A description of threshold conditions is given in the single-particle approach. It is shown that as the observation threshold of amplification without inversion is rather high, and the possibility of experimental realization of FELWI may be essentially impeded
