Nondestructive in situ thermoluminescence using CO(2) laser heating.
We have obtained thermoluminescence glow curves nondestructively from large, solid, ceramic samples by laser spot heating. Although the samples are brittle, laser thermoluminescence glow curves could be obtained with no visible damage to the samples. The experimental glow curves match with theory. By contrast, conventional thermoluminescence measurements require small samples to be removed from a ceramic and placed in a thermoluminescence machine. Laser-induced thermoluminescence glow curves from LiF, silica, and porcelain are presented.
