SCHLIEREN PHOTOGRAPHY USING A MODE-LOCKED LASER AS THE LIGHT SOURCE, (2005)
Hamal,K., DeMichelis,C., Alcock,A. J.
The extremely short pulses of coherent radiation emitted by a mode-locked laser permit the extension of conventional Schlieren photography to events requiring exposure times of a few picoseconds and...
PRODUCTION OF A SPARK BY A TRAIN OF MODE-LOCKED LASER PULSES, (1998)
Alcock,A. J., DeMichelis,C., Richardson,M. C.
The production of a spark in atmospheric air by means of a mode-locked laser beam was investigated and some observations on the breakdown threshold conditions and subsequent development of the spark...
WAVELENGTH DEPENDENCE OF LASER-INDUCED GAS BREAKDOWN USING DYE LASERS, (1998)
Alcock,A. J., DeMichelis,C., Richardson,M. C.
Two tunable dye lasers, operating in the region 7000 to 8500A, have been used to study the wavelength dependence of laser-induced gas breakdown. The results confirm the existence of a threshold...
FREQUENCY BROADENING IN LASER-INDUCED SPARKS, (1998)
Alcock,A. J., DeMichelis,C., Korobkin,V. V., Richardson,M. C.
The spectrum of forward scattered radiation resulting from laser-induced air breakdown has been investigated using a single-mode ruby laser and a mode-locked neodymium glass laser. The broadening...
Lower Hybrid Current Drive in Tore Supra and Jet (1991)
Moreau, D., Gormezano, C., Agarici, G., Agostini, E., Ane, J. M., Auge, N., ...
Recent Lower Hybrid Current Drive (LHCD) experiments in TORE SUPRA and JET are reported. Large multijunction launchers have allowed the coupling of 5 MW to the plasma for several seconds with a...
