Title: | Photothermal deflection mapping of variations in the optical absorption in IR windows | Authors: | REMES, Zdenek NESLADEK, Milos MEYKENS, Kristien Pickles, CSJ Sussman, RS |
Issue Date: | 2000 | Publisher: | WILEY-V C H VERLAG GMBH | Source: | PHYSICA STATUS SOLIDI A-APPLIED RESEARCH, 181(1). p. 115-119 | Abstract: | We used the photothermal deflection (PTD) technique working in a collinear mode to measure optical PTD maps of polished ZnSe, CVD and natural type IIa diamond optical windows at the CO2 laser wavelength (10.6 mu m). This technique is sensitive to inhomogeneous absorption. The variations in PTD signal, present even in single crystal IIa diamond, agree with the interference patterns of both pump and probe laser beams. The interference pattern is discussed in detail. | Notes: | Limburgs Univ Centrum, Inst Mat Res, Div Mat Phys, B-3590 Diepenbeek, Belgium.
