Description
Reported here is the first cryogenically-cooled performance of Er3+-doped Y2O3 laser based on 4I11/2 → 4I13/2 transitions. Laser material was diode-pumped directly into an upper laser manifold 4I11/2 in order to minimize quantum defect of this Mid-IR laser. CW output power of over 1.6 W at ∼ 2.7 μm was achieved with the 27.5% slope efficiency, which is approaching the quantum defect-limited efficiency value despite the marginal optical quality of the available laser sample
