Abstract [en]

The thermal response of optical fibers during CO2 laser irradiation with a wavelength of 10.6 µm has been characterized by use of thermally stable short period fiber Bragg gratings, referred to as chemical composition gratings.Beam profiling of the collimated beam from a CO2laser having a 1/e2 diameter of ~6.5 mm, was performed with a spatial resolution given by the fiber diameter. Heating- and cooling-dynamics of the fiber irradiated with a square pulse with a 1/e rise time of < 1 ms were performed with a temporal resolution down to~250 µs, for temperatures in excess of 1700 ºC.
