    Researchers achieved a 390-femtosecond (fsec) high-power laser pulse using a krypton fluoride (KrF) amplifier. This advancement in high-energy laser systems offers potential for various scientific applications.

    Area of Science:

    • High-energy laser physics
    • Ultrafast optics
    • Plasma physics

    Background:

    • Developing high-power, short-pulse lasers is crucial for advanced scientific research.
    • Krypton fluoride (KrF) lasers offer a potential pathway to high energy and power outputs.

    Purpose of the Study:

    • To characterize the performance of an electron-beam-pumped KrF amplifier for generating high-energy, ultrashort laser pulses.
    • To investigate factors limiting pulse duration and explore nonlinear effects.

    Main Methods:

    • Utilized an electron-beam-pumped KrF amplifier with a 320 cm(2) active cross section.
    • Employed a 210-fsec initial pulse, amplifying it to 390 fsec.
    • Evaluated amplified spontaneous emission (ASE) and nonlinear optical effects.

    Main Results:

    • Achieved a 390-fsec pulse with 4 TW peak power and 1.5 J output energy.
    • Minimized amplified spontaneous emission (ASE) to 1.8% of the total energy.
    • Identified linear dispersion from optical components as the primary cause of pulse broadening.
    • Confirmed negligible nonlinear absorption and self-phase modulation in the CaF(2) output window.

    Conclusions:

    • Demonstrated efficient generation of high-energy, ultrashort pulses from a large-aperture KrF amplifier.
    • Linear dispersion is a key factor in pulse duration limitations for this system.
    • The KrF system shows potential for high-intensity laser applications with minimal nonlinear distortions.
