2.3 kW Cryogenically Cooled Yb:YAG Laser

"Higgs" Factory at the Greek-Turkish Border

“…Nevertheless, it will be challenging to scale up these lasers to kW-level average powers. One notable exception is cryogenically cooled Yb:YAG, with which 2.3 kW CW operation has been demonstrated [11]. In the pulsed regime, 40 mJ pulses at 1 kHz and 15 ps has been generated [12].…”
