Abstract

We present the spectral gain and cavity loss characterisation of an optically-pumped external-cavity 1-μm surface-emitting InGaAs quantum well laser by observing the evolution of intracavity power and spontaneous emission following the uncovering of the cavity mode by an intra-cavity chopper. The smooth monotonic rise (fall) is characteristic of an external-cavity quantum well laser where the photon lifetime is approximately two orders of magnitude higher than the carrier lifetime.
