You can increase the intensity and shift the color of any incandescent
bulb into the blue region while reducing relative power just by using a
thinner filament. That process reduces bulb lifetime however.
The following cites indicate that there is a downside to using a laser
to thin a filament.

http://en.wikipedia.org/wiki/Incande...b#cite_note-24

"Small variations in resistivity along the filament cause "hot spots" to form
at points of higher resistivity; a variation of diameter of only 1% will cause
a 25% reduction in service life. The hot spots evaporate faster than the
rest of the filament, increasing resistance at that point—a positive feedback
which ends in the familiar tiny gap in an otherwise healthy-looking filament."

"In flood lamps used for photographic lighting, the tradeoff is made in the
other direction. Compared to general-service bulbs, for the same power, these
bulbs produce far more light, and (more importantly) light at a higher color
temperature, at the expense of greatly reduced life (which may be as short as
2 hours for a type P1 lamp)."
