Abstract

High power laser sources operating in the 2.1 μm spectral region are useful for ablation of hard tissues, mid-infrared generation and remote sensing of atmospheric CO₂ and H₂O. Although laboratory research has produced constant improvements in the output power (OP) and slope efficiency (SE) of such sources over the last 20 years, their transition outside the laboratory has not yet occurred. Therefore, there is a strong interest to demonstrate a high power and efficient laser output at 2.1 μm in a market-ready, chip-scalable configuration.
