摘要：
We demonstrate a novel continuous-wave 2.1 μm Ho :GTO laser pumped by a laser diode. Employing a pump recycling scheme and 30% output transmittance, we obtain an output power of 4.76 W and a single oscillating peak of 2068.4 nm with a slope efficiency of 55.3% with respect to the absorbed pump power. In addition, the M2 factor of the Ho :GTO laser is reckoned to be approximately 1.3 at the maximum output power.
