A combined experimental setup for OP and ODNMR

Instrumentation for optically-pumped and optically-detected nuclear magnetic resonance (OPNMR and ODNMR) has been developed and implemented as a single experimental apparatus to study semiconductors such as GaAs and CdTe. These two measurement schemes use many of the same components for experiments. Here we describe, in two parts, the apparatus that can record such measurements and give examples of representative data. In Part 1, the radio-frequency probe and low-temperature cryostat are described, including single-channel and two-channel static cryogenic probes that both incorporate a modified solenoid coil that permits better optical access. In Part 2, the optical bench is described in detail, which uses a set of experiments (magneto-photoluminescence, photoluminescence excitation, detection of polarized photoluminescence) as important input for ODNMR. We are able to portray a robust design that encompasses multiple measurement modalities, along with the ability to change many experimental parameters with ease.
