We report on a simple method with a high spectral and spatial resolution for mapping variations in the cavity resonance of a plano-planar broad-area laser based on frequency-selective feedback. The demonstration experiment uses a vertical-cavity surface-emitting-laser (VCSEL), in which growth induced inhomogeneities are of particular importance. It relies only on a standalone laser with a narro...
We present the investigation of the feedback-dependent threshold of an 822 nm wavelength electrically pumped vertical-external-cavity surface-emitting laser (VECSEL). The setup is capable of resolving micrometer-size features on the laser surface, while demanding highly accurate alignment. Modified design criteria are developed, which address this issue, and approaches for the fabrication of mi...

Electrically pumped vertical cavity surface emitting lasers (VCSELs) can produce hundreds of mW's of 976 nm CW output in a TEM00 mode when operated with an external cavity configuration. During pulsed operation (<50ns) a significant increase in the peak power is observed, compared to CW operation. High peak powers makes these lasers very well suited for intra-cavity frequency doubling with a no...
