Temperature effect on emission lines and fluorescence lifetime of the 4F3/2 state of Nd:YVO4

Yanli Mao, Ming‐Ju Huang, Changshun Wang

By measuring the absorption and fluorescence spectra and the fluorescence lifetime of ^{4}F_{3/2} state of Nd^{3+} ions in YVO_{4} (2 at.-{\%}) crystal at different temperature, the effects of temperature on the spectra and the lifetime of ^{4}F_{3/2} state have been investigated. As the temperature is increased, the line width of the ^{4}F_{3/2}-->^4I_{11/2} transitions is found to increase and the spectral line toward the longer wavelength, which are duo to the ion-phonon interaction. The variation fluorescence lifetime of the ^{4}F_{3/2} state of Nd:YVO_{4} is found to be anomalous in the measured range 8-300 K. It is about 81 us at room temperature and decreases to 30 us at 8 K. The experimental results are explained by ascribing to the thermal mixing between the two Stark levels of ^{4}F_{3/2} state with different lifetime.By measuring the absorption and fluorescence spectra and the fluorescence lifetime of ^{4}F_{3/2} state of Nd^{3+} ions in YVO_{4} (2 at.-{\%}) crystal at different temperature, the effects of temperature on the spectra and the lifetime of ^{4}F_{3/2} state have been investigated.

Laser-induced reactions between a Ca+Coulomb crystal and polar molecules

K. Okada, Naoki Kimura, T Suganuma +5 more

We have studied laser-induced reactions between a Ca + Coulomb crystal and the polar molecules of NH 3 and ND 3 at room temperature. The reaction rates of Ca +* (3 d 2 D 3/2 , 4 p 2 P 1/2 ) + NH 3 (ND 3 ) → products have been determined from time variation of the size of fluorescence images of Ca + Coulomb crystals. The results show that the reaction rates are very slow, and therefore the reaction-rate measurements between sympathetically cooled molecular ions and slow NH 3 (ND 3 ) molecules can be performed using a Ca + Coulomb crystal as coolant.We have studied laser-induced reactions between a Ca + Coulomb crystal and the polar molecules of NH 3 and ND 3 at room temperature.
