Abstract

Coherent optical pumping of semiconductor lasers is often used to test the material quality prior to processing and it is an important tool for investigating modem microcavities realized for surface emitting lasers or thresholdless lasers. It is therefore important to delineate in which conditions effects due to the coherence of the pump may occur. Such effects are well-known in gases for example.^[1] The two regions of small and large detuning between the pump and laser field may potentially lead to important effects due to population pulsations.
