    Area of Science:

    • Optics and Photonics
    • Laser Physics
    • Terahertz (THz) Science and Technology

    Background:

    • Dual-wavelength lasers operating in the 1 µm waveband are essential for efficient terahertz (THz) generation.
    • Existing THz generation methods often require complex or bulky laser systems.
    • The development of compact and stable dual-wavelength laser sources is a key research objective.

    Purpose of the Study:

    • To report a novel, compact dual-wavelength vertical-external-cavity surface-emitting laser (VECSEL).
    • To demonstrate stable dual-wavelength oscillation using simple cavity elements.
    • To investigate the tunability and output characteristics of the developed VECSEL for THz applications.

    Main Methods:

    • Design and epitaxial growth of a regularly structured gain chip.
    • Implementation of a standard straight-line laser cavity.
    • Utilizing a blade as a tuning element within the cavity to achieve wavelength selection and dual-wavelength operation.

    Main Results:

    • Stable dual-wavelength oscillation was achieved by positioning the blade at a specific location in the cavity.
    • The laser operated at wavelengths of 961 nm and 970 nm.
    • A total output power of 85 mW was recorded, limited by the available pump source.

    Conclusions:

    • A simple and compact dual-wavelength VECSEL capable of stable oscillation has been successfully demonstrated.
    • The use of a blade as a tuning element offers a straightforward method for achieving dual-wavelength operation.
    • This laser architecture shows promise as a cost-effective and efficient light source for terahertz generation.
