  • Ultrashort pulse amplification in cryogenically cooled amplifiers
    Patent number: 6804287
    Abstract: A laser amplifier system amplifies pulses in a single “stage” from ˜10−9 joules to more than 10−3 joules, with average power of 1-10 watts, and beam quality M2<2. The laser medium is cooled substantially below room temperature, as a means to improve the optical and thermal characteristics of the medium. This is done with the medium inside a sealed, evacuated or purged cell to avoid moisture or other materials condensing on the surface. A “seed” pulse from a separate laser is passed through the laser medium, one or more times, in any of a variety of configurations including single-pass, multiple-pass, and regenerative amplifier configurations.
