We report a compact, cryogenic Yb:YAG regenerative amplifier that delivers >19-mJ energy pulses at 1-kHz with near-TEM00 spatial profile. The excellent power and pointing stabilities are ideal for OPCPA pumping over weeks-long continuous operation.

We report a robust long-term stable >19mJ energy, 1kHz repetition rate cryogenic Yb:YAG regenerative amplifier and its application in pumping a mJ-class, 3µm wavelength OPCPA. We highlight the benefits of cryo-Yb:YAG over alternative systems.

Directed energy propulsion for interstellar travel has been proposed as an ideal method for reaching appreciable speeds relative to the speed of light: 0.2c. However, the amount of energy required necessitates a large aperture, on the order of kilome
