Abstract

The determination of small signal gain in candidate laser systems, especially low gain chemically pumped lasers, is a challenging problem. In this paper we discuss a new approach to this problem using tunable diode lasers as sensitive probes for optical gain. The gain diagnostic was verified on optically pumped molecular iodine. Small signal gains of 10⁴ were detectable with signal to noise exceeding 10. The gain diagnostic was also applied to a candidate chemically pumped laser system, the oxygen pumped IF laser.
