  • Patent number: 10734779
    Abstract: The present application is applicable to laser technology field and provides a dual-wavelength synchronous pulsed fiber laser based on rare earth ions co-doped fiber, which includes a continuous light LD pumping source, a rare earth ions co-doped fiber and two resonant cavities. Sensitizing ions in the rare earth ions co-doped fiber absorb the pumping light and radiate laser of one wavelength. Meanwhile, sensitized ions in the rare earth ions co-doped fiber radiate laser of another wavelength. Laser generated by sensitizing ions is subjected to Q-switching or mode locking with the saturable absorber inserted in the cavity to generate pulsed laser. Generation and partial reabsorption for the pulsed laser modulates gain of the laser radiated by sensitized ions periodically and generates synchronous pulsed laser, thereby implementing a dual-wavelength synchronous pulsed fiber laser.

  • Publication number: 20200236597
    Abstract: In various embodiments, an access point sends a first frame. The first frame carries a TXOP handover enforcement THE indication field which is a first value or a second value. The first value instructs a station that has accessed a channel to hand over a held TXOP to the access point, and the second value instructs the station that has accessed the channel to hand over the held TXOP to the access point when a handover condition is satisfied. It can be learned that the STA hands over the held TXOP to the AP. Therefore, the AP may be a TXOP holder through the TXOP handover even if the AP fails to obtain the channel through contention, so that a probability of holding the TXOP by the AP is improved, a probability of scheduling a STA by the AP is improved, and system resource utilization is improved.
