Abstract
For the first time, to the best of our knowledge, we demonstrate an efficient continuous-wave Ho : LSO laser dual-end-pumped by a fiber-coupled laser diode at 1.94 μm. We show that the elaborated Ho : LSO laser produces 5.8 W output power at 2106.55 nm, corresponding to a slope efficiency of 37.7% with respect to the absorbed pump power. In addition, the beam quality factors M2 are 1.5 and 1.7 in the horizontal and vertical directions, respectively, at the maximum output power.
