This article describes work I did to improve an existing infrared lamp heater in a so called horizontal geometry MOCVD reactor. ZEMAX was used to model and optimize the heater geometry using non-sequential ray-tracing.

This paper described work undertaken at the University of Bern to model the cavity of a side-pumped Nd: YVO₄ laser using ZEMAX to compute the absorbed power in the laser rods and the LASCAD program to compute the resulting cavity modes.
