论文摘要
High-power femtosecond lasers beyond 5 μm are attractive for strong-field physics with mid-infrared (IR) fields but are difficult to scale up. In optical parametric chirped-pulse amplification (OPCPA) at mid-IR wavelengths, a nonlinear crystal is vital, and its transmittance, dispersion, nonlinear coefficient, and size determine the achievable power and wavelength. OPCPA beyond 5 μm routinely relies on semiconductor crystals because common oxide crystals are not transparent in this spectral range. However, the small size and low damage threshold of semiconductor crystals fundamentally limit the peak power to gigawatts. In this paper, we design a terawatt-class OPCPA system at 5.2 μm based on a new kind of oxide crystal of La<sub>3</sub>Ga<sub>5.5</sub>Nb<sub>0.5</sub>O<sub>14</sub> (LGN). The extended transparent range, high damage threshold, superior phase-matching characteristics, and large size of LGN enable the generation of 0.13-TW seven-cycle pulses at 5.2 μm. This design fully relies on the state-of-the-art OPCPA technology of an octave-spanning ultrafast Ti:sapphire laser and a thin-disk Yb:YAG laser, offering the performance characteristics of high power, a high repetition rate, and a stable carrier-envelope phase.
