Abstract

Er,Cr:YScGG is an important laser material for medical applications in the mid-infrared because of the strong absorption of its 2794 nm line in water. This wavelength has been demonstrated to have reasonably high transmission in hollow glass waveguides, making a practical and convenient delivery system for the beam. These waveguides, however, are sensitive to mode quality and have been tested only with low power TEM_oo lasers. We decided, therefore, to examine the transmission of these waveguides when the laser runs at high power (up to 12 W) and multimode, but with some effort to minimize M² without undue compromise in power
