Laser systems with diamond optical elements
J Russell Seitz
- 17 Sep 1973
TL;DR: High power laser systems with optical elements of diamond having a thermal conductivity of at least 10 watts/cm* K at 300*K were considered in this paper. But the performance of these systems was limited by the fact that the optical element of diamond has no optical absorption at the laser beam wavelength of no more than 20%.
