Laser Waveguides by a Hybrid Ceramic Process
We used a novel approach to produce a ceramic waveguide with a complex geometry with the composition Cr<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sup>+:YAGIYb:YAG/YAG, as shown in Fig. 1. The bulk YAG allows a more efficient dissipation of the heat generated in the waveguide to the cooling system, thanks to its higher thermal conductivity [1]. The Cr<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sup>+: YAG cladding serves to suppress amplified spontaneous emission (ASE), since Cr<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sup>+ has a very strong absorption near the lasing wavelength [2].
