We demonstrate experimentally the onset of cascaded optical parametric amplification (COPA) in periodically-poled lithium niobate. This technique permits narrowband terahertz wave generation beyond the Manley-Rowe limit.
We present a compact and robust cryogenically cooled Yb:YAG chirped pulse amplifier with 250W of average power at a repetition rate of 100 kHz with a near-diffraction limited beam quality.
A cryogenically cooled Yb:YAG amplifier with 4.7-ps laser pulses is employed to generate 100-GHz pulses in lithium niobate via optical rectification. We obtained a high efficiency ∼0.05% at 300 K, close to the theoretical prediction.
We demonstrate cascaded optical parametric amplification (COPA) as a promising pathway for efficient generation of THz-waves beyond the Manley-Rowe limit. The spectro-temporal characterization of this novel regime of parametric amplification is reported.
A family of approaches employing sequences of optical pump pulses, yielding energy conversion efficiencies in the 5–10% range, is introduced. A method to generate these sequences by cascaded optical parametric amplification of narrowband pulses is discussed.
We report on the theoretical and experimental spectro-temporal characterization of cascaded optical parametric amplification as a promising novel method for efficient THz wave generation.
We have begun building the “Mercury” laser system as the first in a series of new generation diode-pumped solid-state lasers for inertial fusion research. Mercury will integrate three key technologies: diodes, crystals, and gas cooling, within a unique laser architecture that is scalable to kilojoule and megajoule energy levels for fusion energy applications. The primary near-term performance goals...
