Spectral gain and cavity loss characterization of an optically-pumped external-cavity surface-emitting quantum well laser
Spectral gain and cavity loss characterization of an optically-pumped external-cavity surface-emitting quantum well laser
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.

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.
