Abstract :
Laser experiments on thulium-gadolinium-lutetium-yttrium co-doped monoclinic potassium double tungstates in buried, ridge-type channel-waveguide geometry demonstrate maximum slope efficiencies approaching twice the Stokes limit at ~1.9 μm, when pumping with a Ti:Sapphire laser at 800 nm.
