Abstract

Fiber-optic light pipes have unique advantages for optical spectroscopy in extreme environments: at low-temperatures where optical windows on cryostats are prohibitive; in small-bore high-field magnets; and in high-pressure cells. Practical applications are described for a variety of techniques including photoluminescence, photoreflectivity, Faraday rotation, optical transmission, and even Raman light scattering. To illustrate the utility of these fiber-optic systems, results are presented for experiments to T=0.1 K and up to B=30 tesla on magnetic semiconductors (Cd,Mn)Te and GaAs quantum well systems.
