title: High-density, high-temperature alkali vapor cell.
abstract: We present a vapor cell design that enables resonant optical spectroscopy in high-density, high-temperature alkali metal vapors. Optical access is provided via reflection from the interface between the vapor and a sapphire window. The cell resists corrosion from the highly reactive alkali vapors, in our case, potassium, up to 800 degrees C (number densities up to 10(19) cm(-3)). The cells maintain their integrity for an average of 100 h above 500 degrees C with about 10 heating/cooling cycles.
