Efficient tunable diode pumped CW Yb:LSO laser

We demonstrate an efficient tunable diode-end-pumped continuous wave (CW) Yb3+:Lu2SiO5 (Yb:LSO) laser. With a 5 at.-% Yb3+-doped sample, we obtained 3.24-W output at 1080 nm for 7.3 W of absorbed pump power, the corresponding slope efficiency was 55%. And the laser wavelength could be tuned from 101
