High-energy and high-average-power two-channel Yb:YAG amplifier with passive coherent combining
A two-channel laser amplifier with passive coherent combining based on Yb:YAG active elements with bright diode end pumping was developed. The pulse energy limits of a one-channel scheme are investigated, and the ability to double pulse energy in the two-channel scheme is demonstrated. 10 mJ pulse e...

| Zusammenfassung: | A two-channel laser amplifier with passive coherent combining based on Yb:YAG active elements with bright diode end pumping was developed. The pulse energy limits of a one-channel scheme are investigated, and the ability to double pulse energy in the two-channel scheme is demonstrated. 10 mJ pulse energy at a repetition rate of 1.5 kHz and 5 mJ at 6 kHz simultaneously with high gain and perfect beam quality at coherent combining efficiency over 97% was achieved. |
