Solicitation from the Department of Energy: The National Renewable Energy Laboratory (NREL) is seeking a Tunable Nd: YAG Pumped Laser System (Quantity 1). This laser system is crucial for conducting time-resolved microwave conductivity (TRMC) and time-resolved dielectric loss (TRDL) spectroscopy measurements. The system will support the Solar Photochemistry core program, the BioLec EFRC, and the SPECS EFRC, ensuring reliable access to TRMC and TRDL measurements for present and future projects.
