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 ...

Single-Ended Infrared Photothermal Radiometric Measurement of Quantum Efficiency and Metastable Lifetime in Solid-State Laser Materials: The Case of Ruby (Cr3+: Al2O3)
Mandelis, Andreas; Munidasa, M.; Othonos, Andreas S. (1993)A new, simple, and self-consistent frequency-scanned photothermal radiometric (PTR) detection scheme was applied to the measurement of the metastable state de-excitation parameters of a ruby laser rod. From the extrema of ...
