This paper describes the mechanism underpinning modal staging behaviour in screeching jets. An upstream-propagating subsonic guided-jet mode is shown to be active in all stages of screech. Axial variation of shock-cell spacing manifests in the spectr

Concentration dependence of energy transfer upconversion in Nd:YAG

Autor: Yoon, S. J., Yan, R. P., Beecher, S. J., Jacob Mackenzie

Publikováno v: Scopus-Elsevier

The concentration dependence of energy transfer upconversion in Nd:YAG is investigated via the z-scan technique. The ETU coefficient is determined to increase from 35×10-18 cm3/s to 90×10-18 cm3/s when the concentration increases from 0.3 at.% to 1
