    A new terahertz-wave parametric generator offers smooth tuning from 0.6-2.6 THz using MgO:LiNbO(3) crystals. This system enables efficient terahertz-wave absorption measurements across a broad frequency range.

    Area of Science:

    • Optics and Photonics
    • Terahertz Spectroscopy

    Background:

    • Terahertz (THz) wave generation is crucial for spectroscopy.
    • Achieving wide-tuning-range THz sources with stable output remains a challenge.

    Purpose of the Study:

    • To construct an achromatically injection-seeded terahertz-wave parametric generator (TS-TPG).
    • To demonstrate wide-range, smooth tuning of THz waves by adjusting the seeder wavelength.
    • To validate the system's utility for THz absorption measurements.

    Main Methods:

    • Utilized MgO:LiNbO(3) crystals in a dispersion-compensated optical setup.
    • Employed an injection-seeding technique with a tunable laser.
    • Configured a stationary optical arrangement without mirror readjustment for tuning.

    Main Results:

    • Achieved smooth tuning of THz waves from 0.6 to 2.6 THz solely by adjusting the seeder wavelength.
    • Demonstrated the system's capability for wide-frequency-range THz-wave absorption measurements.
    • Successfully measured absorption spectra of low-pressure water vapor.

    Conclusions:

    • The developed TS-TPG system provides a versatile and efficient platform for THz spectroscopy.
    • The simple tuning mechanism simplifies THz wave generation and application.
    • This technology facilitates advanced THz absorption studies over extended spectral regions.
