The real potential of inversionless lasing lies in the utilization of mismatched schemes, leading to compact high-frequency laser sources. A comparative study of a matched and a mismatched system is made in which all parameters are made equal except the transition wavelengths. Theory is presented to relate the appropriate element of the resulting density matrix to the absolute absorption or gain that may be experimentally observed. This facilitates the study of possible atomic systems that may provide mismatched gain in a Doppler-broadened regime. Experimental investigations into the production of inversionless gain at 422 nm in a Doppler-broadened, mismatched rubidium system are reported.
