帮我检查逻辑并按照SCI论文标准润色下面这段话并尽量减少分句：Tm3+ as a sensitizer which enables this system to be directly pumped by commercial LDs operating at 781 or 785 nm and the two-for-one cross-relaxation mechanism of Tm3+

Tm3+ serves as a sensitizer in this system, allowing for direct pumping by commercial LDs operating at 781 or 785 nm. Additionally, the two-for-one cross-relaxation mechanism of Tm3+ ensures high pump quantum efficiency. As a result of a quick energy transfer from Tm3+, the upper laser level of Ho3+ is populated, ultimately leading to laser action.
