Sveinn: The feeble laser 10ns, 100mw pulse is the sole initiator of this if he is hitting different amount of p(0) or d(0) the correlated amount of particle current is generated…. For comparison, A laser pointer can produce a green light. High-end: <http://www.wickedlasers.com/lasers/Elite_Pro-89-37.html> Wicked Lasers E2 Elite Fusion. $199.00 Wavelength: 532nm. Power: 150mW. It looks like the reason that this green laser frequency works for the Swedes has a lot to do with the nanostructure of the Shell 105 catalyst. It is most unusual and it is doubtful that an experimenter could find anything similar with a nickel catalyst. Anyway, the combo seems to have been an “inspired” choice, to use this frequency of light with this particular catalyst. If they had opted for the red frequency of the Letts/Cravens effect, it possibly would have been too long and not worked. There are several good images here (worth a thousand words) which show the hexagonal porosity of the iron oxide - and the uniform dimension of the openings which is larger than the wavelength of the laser light – but not much larger. http://www.sciencedirect.com/science/article/pii/S2352214315000106 I realize this is a simulation, but other references indicate that this particular catalyst has natural, uniform porosity. However, this geometry does not seem to support the likelihood of DCE as soundly as if it was larger (2 nm).
