Paper 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.
