They don't need to determine the power of the laser beam. They already know how much energy is in it (because they put it there), and they know how long a pulse lasts, hence they know the power. The word "corroborate" in this case refers to the momentary strength of the magnetic field that was generated. They mention the power of the laser beam only because it was a parameter of the experiment. > >I believe you misread the sentence. > > > > >On Mon, Apr 1, 2013 at 9:28 PM, <mix...@bigpond.com> wrote: > >> In reply to Axil Axil's message of Mon, 1 Apr 2013 19:06:00 -0400: >> Hi, >> [snip] >> >W&L now includes a reference to spasers in the following on page 26: >> > >> > >> http://www.google.com/url?sa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=11&cad=rja&ved=0CDEQFjAAOAo&url=http%3A%2F%2Fnewenergytimes.com%2Fv2%2Fsr%2FWL%2Fslides%2F20120706LatticeEnergySlides.pdf&ei=JxBaUbmTJarC4AOe1oHoCA&usg=AFQjCNGIA5OCFP0wCWogsAF0RiKYCnMwRA&sig2=EZC1zIg_0FxZ6I_Rwjfo1A >> > >> > they site this info >> > >> >"We demonstrate that aligned carbon-nanotube arrays are efficient >> >transporters of laser-generated mega-ampere electron currents over >> >distances as large as a millimeter.
