About
The Photoluminescence setup is on the same optical table as the Hologaphic Lithography setup.
This custom setup is used for materials characterization including crystal growth quality and gain region/quantum well growth, or semiconductor alloy ratio. Multiple laser sources are available - including the He-Cd laser also used for Holography, via a flip-down mirror.
Light is delivered in free-space, selected via magnetic flip-mirrors, and collected by optical fiber, and analyzed by a USB spectrometer.
