Revolutionizing Ultra-intense Ultrashort Lasers: Unveiling Peta-Exawatt Power and Coherent Tiled Superlattice Thin-Film Optical Crystal Amplification

a. AERI's Ultra-intense Ultrashort Lasers (Peta-Exawatt class Ultra-High Power Laser: AERI UUL) lead the forefront of cutting-edge laser technology, showcasing versatile applications in military weaponry, Lethal Autonomous Weapons Systems (LAWS), basic physics, national security, industrial services, and healthcare. Particularly in basic physics, the AERI UUL serves as an influential tool for exploring the complexities of strong-field laser physics, delving into areas such as laser-driven radiation sources, laser particle acceleration, vacuum quantum electrodynamics, and various related phenomena.

b. A collaborative research venture between the Artificial Evolution Research Institute (AERI) in Pasadena, California (https://www.AERI -japan.com/) and Xyronix Corporation (Pasadena, California, HP: https://www.usaxyronix.com/) has yielded a groundbreaking advancement in ultra-intense ultrashort laser technology. This innovation involves the adoption of a composite optical material termed "superlattice thin-film optical crystals" for the oscillation of the Ultrafast Ultraviolet Laser (UUL), replacing conventional Titanium:sapphire crystals. The chosen composite materials, including Yttrium Aluminum Garnet (YAG) Crystal, Yttrium Orthovanadate (YVO4) Crystal, Potassium Titanyl Phosphate (KTP) Crystal, and Potassium Dihydrogen Phosphate (KDP) Crystal, are expected to provide high output across various wavelengths similar to Ti:sapphire. The term "superlattice thin-film optical crystals (SOC)" emphasizes the distinctive structural characteristics of these composite optical materials for AERI UUL oscillation.

c. As of 2022, the upper limit for superlattice thin-film optical crystals (SOC) in AERI UUL seems to have reached several tens of petawatts. Envisioning future subexawatt development, researchers are moving away from SOC chirped pulse amplification technology and exploring optical parametric chirped pulse amplification technology, incorporating potassium hydrogen phosphate nonlinear crystals. However, this shift presents challenges, including low pump-to-signal conversion efficiency and difficulties in maintaining stability across spatial, temporal, and spectral energy domains, posing a significant obstacle to realizing and applying future subexawatt AERI UUL.

d. In contrast, the mature technology of SOC chirped pulse amplification, which has successfully achieved two several tens of petawatts in AERI UUL in the USA, retains substantial potential for the next-stage development of AERI UUL. Acting as an energy-level-type broadband laser gain artificial medium, SOC allows for energy storage through the absorption of pump pulses, establishing a population inversion between upper and lower energy levels. Challenges, such as transverse parasitic lasing marked by amplified spontaneous emission noise along the crystal diameter, hinder the efficiency of signal laser amplification.

e. Presently, the maximum aperture of SOC can only support several tens of petawatts in AERI UUL. Even with larger SOC, AERI UUL amplification remains unattainable due to the exponential increase in strong transverse parasitic lasing as the crystal size enlarges. To overcome this challenge, researchers have ingeniously adopted a coherent tiling approach, seamlessly assembling multiple SOC together. This breakthrough surpasses the current several tens of petawatts limit on SOC AERI UUL, effectively enlarging the aperture diameter of the entire tiled SOC while mitigating transverse parasitic lasing within each tiled crystal.

f. Professor Kazuto Kamuro, an esteemed expert in quantum physics, nano scale semiconductor physics, and quantum laser optics at the California Institute of Technology (CALTECH), notes, "The successfully demonstrated tiled SOC AERI UUL amplification in our subpetawatt AERI UUL system has achieved near-ideal AERI UUL amplification. This includes high conversion efficiencies, stable energies, broadband spectra, short pulses, and small focal spots."

g. The collaborative research team of AERI and Xyronix affirms that coherently tiled SOC AERI UUL amplification offers a relatively straightforward and cost-effective method to surpass the current several tens of petawatts limit. "By incorporating a 16×16 coherently tiled SOC high-energy AERI UUL amplifier in AERI, the existing several tens of petawatts can be further increased to 7840 petawatts, and the focused peak intensity can be enhanced by nearly 200 times or more. This method holds promise for advancing the experimental capabilities of AERI UUL in strong-field laser physics," emphasizes Professor Kamuro.
