Greater than 2 kW all-passive fiber Raman amplifier with good beam quality
Yizhu Chen... and Pu Zhou|Show fewer author(s)
We report a 2 kW all-fiberized Raman fiber amplifier with efficient brightness enhancement based on the graded-index fiber. The maximum power output reaches up to 2.034 kW centered at 1130 nm, with a conversion efficiency of 79.35

Mid-infrared optical frequency comb in the 2.7–4.0 μm range via difference frequency generation from a compact laser system
Lian Zhou... and Wenxue Li|Show fewer author(s)
We report on the generation of a mid-infrared (mid-IR) frequency comb with a maximum average output power of 250 mW and tunability in the 2.7–4.0 μm region. The approach is based on a single-stage difference frequency generation (

35 W continuous-wave Ho:YAG single-crystal fiber laser
Yongguang Zhao... and Valentin Petrov|Show fewer author(s)
We report on a high-power Ho:YAG single-crystal fiber (SCF) laser inband pumped by a high-brightness Tm-fiber laser at 1908 nm. The Ho:YAG SCF grown by the micro-pulling-down technique exhibits a propagation loss of $0.05\pm 0.005

Pushing the boundaries of diode-pumped solid-state lasers for high-energy applications
Saumyabrata Banerjee... and John Collier|Show fewer author(s)
We report on the successful demonstration of a 150 J nanosecond pulsed cryogenic gas cooled, diode-pumped multi-slab Yb:YAG laser operating at 1 Hz. To the best of our knowledge, this is the highest energy ever recorded for a diod
