Out of the blue: semiconductor laser pumped visible rare‐earth doped lasers

Abstract The rise of semiconductor‐based pump sources such as In x Ga 1‐x N‐laser diodes or frequency‐doubled optically pumped semiconductor lasers with emission wavelengths in the blue encourages a revisitation of the rare‐earth ions Pr 3+ , Sm 3+ , Tb 3+ , Dy 3+ , Ho 3+ and Er 3+ with respect to t...
