Abstract:

The main objective of this research program is to study the optical properties of materials suitable for use as low loss windows and other optical components in the HF, DF and CO2 laser wavelength regions. In order to investigate these materials, measurements of the absorption coefficient were undertaken using laser calorimetry and infrared spectroscopy. To further this investigation, absorption at the surfaces of window materials was measured. This involved solving the classical heat flow problem using parameters gained from the experiment.
