摘要：
A team of researchers demonstrated a 4.2-W Yb:Y2O3 laser with a 96 percent output coupler and with an input pump power of 19.5 W. The corresponding slope efficiency was 29 percent, and a beam-quality measurement yielded an M2 of ∼200 μm. Wavelength shift was observed as the output coupling varied and pump power changed.
