    • Foam-based optical absorber for high-power laser radiometry 

      Ramadurai, Krishna; Cromer, Christopher L.; Li, Xiaoyu; Mahajan, Roop L.; Lehman, John H. (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 ...
    • High-performance carbon nanotube coatings for high-power laser radiometry 

      Ramadurai, Krishna; Cromer, Christopher L.; Lewis, Laurence A.; Hurst, Katherine E.; Dillon, Anne C.; Mahajan, Roop L.; Lehman, John H. (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 ...
