  Thulium-doped fiber lasers: the latest revolution in high-power fiber technology
  With output power levels now approaching the kW level, Tm-doped fiber lasers are beginning to emerge as the latest revolution in high-power fiber laser technology. Operating at 1.9–2.1 µm, this technology falls into the eye-safer category of lasers, giving it potential advantages over 1 µm lasers for industrial and military directed energy applications. The greater potential for pulse scaling is also beginning to be realized with peak powers now approaching 100 kW without requiring excessively complicated fiber designs or sacrificing beam quality.
