Abstract

Thanks to a high atmospheric transmission, 2 μm fiber lasers offer unique benefits for both civil and military applications, such as LIDAR, laser weapons or optical countermeasures. All-fibered sources are of particular interest since they allow compact, robust and alignment-free systems. Furthermore, they are well-suitable for power upscaling thanks to a good thermal dissipation. We present in this contribution the recent results achieved on 2 μm fiber lasers and fibered components allowing all-fibered architectures. In particular, the power upscaling up to 500 W-class and the efficiency of Tm³⁺ -doped and Tm³⁺, Ho³⁺ -codoped fiber lasers are discussed.
