15W diode-pumped Tm:YAG double-clad waveguide laser
15W diode-pumped Tm:YAG double-clad waveguide laser
We present results for a planar direct-bonded double-clad waveguide comprised of a Tm:YAG core, undoped YAG inner-cladding, and sapphire outer-cladding layers. The YAG/sapphire numerical aperture is sufficient to capture most of the highly divergent radiation of a laser diode, thus allowing a side-pumped arrangement with two proximity-coupled λp = 785 nm, 20 W diode bars. This simple and efficient pumping scheme, combined with the thin waveguide dimension, leads to a high pumping intensity, as required for efficient operation of quasi-three-level laser systems.

Abstract
We present results for a planar direct-bonded double-clad waveguide comprised of a Tm:YAG core, undoped YAG inner-cladding, and sapphire outer-cladding layers. The YAG/sapphire numerical aperture is sufficient to capture most of the highly divergent radiation of a laser diode, thus allowing a side-pumped arrangement with two proximity-coupled λp = 785 nm, 20 W diode bars. This simple and efficient pumping scheme, combined with the thin waveguide dimension, leads to a high pumping intensity, as required for efficient operation of quasi-three-level laser systems.
