Degree of mode localization in Random lasing from ZnO nanoparticles

FALLERT, Johannes; SARTOR, Janos; DIETZ, Roman J. B.; SCHNEIDER, Daniel; ZALAMAI, Victor; KLINGSHIRN, Claus; KALT, Heinz (IEEE, 2009)

We present an experimental procedure to directly extract the degree of localization of random laser modes in ZnO powders. Strongly localized and extended modes are found to coexist within the same ensemble area.
Investigations of external cavity diode lasers: Simulations, analysis and experiments

RADZIUNAS, M.; TRONCIU, V. Z.; LUVSANDAMDIN, E.; KÜRBIS, C.; WICHT, A.; WENZEL, H. (IEEE, 2014)

We report the results of numerical and experimental investigations of the dynamics in an external cavity diode laser device composed of a semiconductor laser and a distant Bragg grating, which provides an optical feedback. ...
Photoluminescence study of /spl alpha/-ZnAl/sub 2/S/sub 4/ single crystals

URSAKI, V.; BOLDURESCU, V.; BURLAKOV, I.; SYRBU, N.; NYARI, T. (IEEE, 2000)

Photoluminescence (PL) spectra of ZnAl/sub 2/S/sub 4/ crystals with spinel structure were studied under the extrinsic excitation. The PL bands at 0.98 eV and 1.34 eV are suggested to be caused by native defects; while the ...
