  • Optical adaptive device and wearable device
    Patent number: 11822085
    Abstract: The present disclosure provides an optical adaptive device and a wearable device. The optical adaptive device includes a carrier, a first light adjusting element, and a second light adjusting element. The first light adjusting element is in or on the carrier and configured to focus a first light from a first article on a visual area. The second light adjusting element is in or on the carrier and configured to focus a second light from a second article on the visual area. The second article is further away from the area than the first article.

  • Laser apparatus and laser generation method
    Patent number: 10224690
    Abstract: A laser apparatus is provided, which includes an optical reflection and gain unit, an optical modulation unit and a polarizing selection unit. The optical reflection and gain unit includes a gain medium and at least two dichroic surfaces, and is configured to generate a laser beam. The optical modulation unit and the optical reflection and gain unit form a cavity, and the optical modulation unit is configured to adjust phase boundary conditions of the cavity. The optical modulation unit includes portions that respectively correspond to optical phase boundaries in the cavity, so as to allow an optical field in the cavity to pass through the optical modulation unit at least twice. The polarizing selection unit is disposed between the optical reflection and gain unit and the optical modulation unit, and is configured to adjust the polarizing direction of the optical field incident to the optical modulation unit.
