As a sensitizer, Tm3+ enables this system to be directly pumped by commercial LDs operating at 781 or 785 nm. Additionally, the two-for-one cross-relaxation mechanism of Tm3+ provides high pump quantum efficiency. Following a quick energy transfer from Tm3+, the upper laser level of Ho3+ is populated, leading to laser action.
