According to SCI requirements, the polished paper should be modified as little as possible:

Tm-Ho co-doped materials are ideal candidates for miniaturized laser systems due to their efficient cross-relaxation and rapid energy transfer processes. However, the harmful up-conversion process generates excessive heat, which poses challenges for heat management and limits both high power output and good beam quality.
