Foam-based optical absorber for high-power laser radiometry
(Optical Society of America, 2007-12-01)
We report damage threshold measurements of novel absorbers comprised of either liquid-cooled silicon carbide or vitreous carbon foams. The measurements demonstrate damage thresholds up to 1.6 x 104 W/cm(2) at an incident ...
Laser-induced exfoliation of amorphous carbon layer on an individual multiwall carbon nanotube
(AIP Publishing, 2007-07)
Pulsed laser treatment of an individual multiwall carbon nanotube induced selective exfoliation of the amorphous carbon contamination layer. The multiwall carbon nanotube (MWCNT) was exposed to a 248 nm excimer laser. After ...
High-performance carbon nanotube coatings for high-power laser radiometry
(American Institute of Physics, 2008-01-01)
Radiometry for the next generation of high-efficiency, high-power industrial lasers requires thermal management at optical power levels exceeding 10 kW. Laser damage and thermal transport present fundamental challenges for ...
