Yanrong Song 1*<br />
We introduce a novel kind <strong>of</strong> laser-vertical external cavity surface emitting laser which<br />
combinds the advantages <strong>of</strong> solid state lasers <strong>and</strong> semiconductor lasers. The design <strong>of</strong> the gain chip,<br />
microavity <strong>and</strong> the whole setup are given <strong>and</strong> a comprehensive modeling <strong>of</strong> vertical-external-cavity<br />
surface-emitting laser, reflective spectrum, edge-emitting photoluminescence spectrum, surfaceemitting<br />
photoluminescence spectrum, material gain spectrum <strong>and</strong> the output characteristics are<br />
calculated. The experiments about CW laser, double frequency output, mode locking laser are<br />
demonstrated.<br />
BIO: Pr<strong>of</strong>. Yanrong Song works in College <strong>of</strong> Applied Sciences, Beijing University <strong>of</strong><br />
