Reported in U. of Rochester web anouncements a femtosecod pulsed laser exposure to a tungsten light filament would increse the light production eficiency by 50%. This would be something of interest to CICESE's optics department! The current proposued theory is that the femtosecond laser, which is well known to cause the formation of nanometer sized particles and defects, gives the material a complex three dimensional structure with varialions smaller then a light wavelength. How this couples into light will described in the forthcomming publication in Physical Review Letters.
