Threshold for FELWI operation
Karen Badikyan
TL;DR
This paper investigates the threshold conditions for free electron laser without inversion (FELWI), revealing that high intensity thresholds hinder experimental realization of FELWI in the collective approach.
Contribution
It provides a theoretical analysis of the threshold behavior for FELWI operation, highlighting the high intensity requirements in the collective approach.
Findings
Threshold for FELWI depends on amplified wave intensity.
High threshold hampers experimental realization.
Collective approach describes the threshold conditions.
Abstract
It is shown that the possibility to create the free electron laser without inversion (FELWI) has a threshold behavior on the field of intensity of amplified wave. In the collective approach, the description of threshold conditions is given. It is shown that the threshold of observation of amplification without inversion is sufficiently high, which hampers essentially the possibility of experimental realization of the FELWI.
