Abstract

Strong blue emissions have been observed in fluoride crystals, such as LiYF4, BaY2F8, and KYF4, codoped with Tm3+ and Yb3+ when excited into the Tm3+ 3F4 state at ∼780 nm. Energy transfer from Tm3+ to Yb3+ ions followed by the transfer from Yb3+ to Tm3+ was demonstrated to be responsible for the upconversion process. A pumping scheme is proposed based on this upconversion mechanism for blue-laser applications using these materials.
