This paper reports a study of the effect of laser pulse repetition rate and substrate temperature on the properties of crystalline Sc2O3 films grown on -oriented sapphire via pulsed laser deposition (PLD). For the range of substrate laser-heating pow

We present the hetero-epitaxial growth of high-quality crystalline Y _3 Ga _5 O _12 onto a 〈100〉-oriented YAG substrate via pulsed laser deposition, using mixed ternary-compound and segmented binary-compound targets. We observe that a Y _3 Ga _5

In this Special Issue on Cryogenically Cooled Lasers, we capture a snapshot of the state-of-the-art laser systems that capitalise on the benefits of operating the gain material at cryogenic temperatures. The principle of operating a solid-state laser

Tm-doped Ta2O5 films, deposited on thermally oxidized silicon substrates, were etched to form rib waveguides. Optically pumped (793 nm) multimode lasing at 1.9 µm is demonstrated from bare facets, producing 24-mW output, 46% slope efficiency.
