Ultra-broad absorption band of a Dy 3+ -doped Gd 3 Sc 2 Al 3 O 12 garnet crystal at around 450 nm: a potential crystal for InGaN LD-pumped all-solid-state yellow lasers

The 2 at% Dy 3+ doped Gd 3 Sc 2 Al 3 O 12 single crystal is potential for InGaN LD-pumped all-solid-state yellow lasers application with an ultra-broad absorption band (FWHM = 31 nm) at 447 nm.
