Diagnostics of nonradiative defects in the bulk and surface of brewster-cut Ti:sapphire laser materials using photothermal radiometry
(1997)The understanding of the problem of nonradiative energy conversion in solid-state laser materials is a key factor in improving the overall efficiency of solid-state lasers. Furthermore, the reduction of the heat generated ...

Photothermal radiometry on nickel (pigmented aluminium oxide) selective solar absorbing surface coatings
(1998)Photothermal radiometry (PTR) is applied to characterize nickel-pigmented aluminium oxide solar absorbing coatings. A modulated laser beam is used to heat the solar samples. The subsequent emission of thermal radiation is ...
