Latest Patents

Ko's latest patents include a self-seeding method and apparatus for a dual cavity type tunable laser. This invention utilizes both first diffracted beams and 0th diffracted beams, allowing for the internal provision of two oscillators. By employing a diffraction grating and sharing a single medium, the system effectively designates one oscillator as the master and the other as the slave. This design minimizes the need for additional optical devices. Furthermore, the invention features a single partially reflecting mirror at the output of a grazing incidence with tuning mirror (GIM) type oscillator, facilitating self-seeding and significantly amplifying the laser output while maintaining a consistent oscillation linewidth.

Another notable patent is an apparatus and method for precisely wavelength-tuning single longitudinal mode tunable laser beams. This innovation replaces the traditional tuning mirror with a rotating wedge prism, allowing for precise wavelength adjustments without causing mode hopping. By inserting the wedge prism into the laser resonator, Ko's method ensures that the single longitudinal mode is maintained, resulting in accurate tuning of the laser beams.
