Gallium Oxide (Ga2O3) for Optical Applications

What is it about?

The high laser damage threshold and moderate conductivity of Ga2O3 are leveraged to demonstrate the first Ga2O3‐based laser accelerator and show Ga2O3 as a promising material for high‐power optical applications. With the distinct properties of Ga2O3 combined with advances in fabrication and wafer growth techniques, more Ga2O3‐based high‐power optical applications will be realized in the near future.
