In this article, a diamond anvil cell system for optical studies at variable pressure and at low temperatures is described. A remotely controlled pneumatic driver unit, which consists of a pair of coaxial bellows, operates with helium gas. The setup and techniques for photoreflectance (PR) and time-resolved photoluminescence (TRPL) measurements with a diamond anvil cell are presented. Examples of the application to PR and TRPL in III-V semiconductor alloys under high pressure are shown.
