Thermometric study of CO2-laser heated optical fibers in excess of 1700 degrees C using fiber Bragg gratings
2013 (English)In: Journal of the Optical Society of America. B, Optical physics, ISSN 0740-3224, Vol. 30, no 7, 1835-1842 p.Article in journal (Refereed) Published
The thermal response of optical fibers during CO2 laser irradiation has been characterized by using thermally stable short-period fiber Bragg gratings, referred to as chemical composition gratings. CO2 laser beam profiling was performed by scanning the beam across a 1 mm long grating, providing a spatial resolution given by the fiber diameter. The thermal dynamics during square pulse irradiation has been recorded for temperatures in excess of 1700°C, with heating and cooling rates as high as 10,500°C s−1 and 6500°C s−1, respectively.
