Abstract

Absorption of CW Yb-fiber laser light of 1.07μm wavelength in water has been measured at different water temperatures and laser intensities. The absorption coefficient was estimated to be 0.135cm1 at 25°C water temperature, and this was found to decrease with temperature at a rate of 5.7×104cm1°C1. The absorption coefficient increased significantly when the laser beam was focused in water, and the increase depended on the distance of the focal point from the water surface. This has been attributed to the absorption and scattering losses of laser radiation in a cavity formed in water by the focused beam at laser intensities in the megawatts per square centimeter and higher range.
