Absolute nonradiative energy-conversion-efficiency spectra in Ti3+:Al2O3 crystals measured by noncontact quadrature photopyroelectric spectroscopy
Mandelis, Andreas; Vanniasinkam, J.; Budhudu, S.; Othonos, Andreas S.; Kokta, M. (1993)Photopyroelectric spectroscopy (PPES) was used in a noncontact experimental configuration to obtain high-resolution absolute spectra of the optical-to-thermal energy-conversion efficiency (nonradiative coefficient), ηNR(λ), ...

Diagnostics of nonradiative defects in the bulk and surface of brewster-cut Ti:sapphire laser materials using photothermal radiometry
Vanniasinkam, J.; Munidasa, M.; Othonos, Andreas S.; Kokta, M.; Mandelis, Andreas (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 ...
