  • Patent number: 12339497
    Abstract: The present disclosure provides an optical fiber fusion splicing method, comprising: performing a slit operation on the coating layer at a preset stripping length of the optical fiber to be fused; immersing the optical fiber in a softening liquid to soften the coating layer after the slit is formed; taking out the optical fiber and applying a force in an axial direction of the optical fiber to strip the softened coating layer; cutting an end of the optical fiber after the coating layer is stripped, to obtain a fusion end face; fusing two fusion end faces; sleeving a fusion point with a light-transmitting tube, filling the light-transmitting tube with coating glue and then performing a vacuum treatment, and irradiating the light-transmitting tube with an ultraviolet lamp to solidify the coating glue in the light-transmitting tube.

  • Publication number: 20250047062
    Abstract: The present application provides a wave shaping circuit of a laser driving circuit, a laser driving circuit and a laser device, by attenuating the wave at the start of the pulse to a lower power, and then outputting the original pulse power after a delay, the laser relaxation oscillations disappears or occurs at a lower power of the light emission, with which the amplitude and probability of generation of the relaxation oscillations are reduced, thereby reducing the abnormal power at the moment of pulse operation and preventing the optical fiber from being overheated and damaged.

  • Patent number: 11005229
    Abstract: An all solid-state laser light source device comprises a diode-pump laser and the following devices sequentially arranged in an optical path direction of laser light: a coupling optical fiber, a coupling lens assembly, and a resonant cavity. An anisotropic laser crystal is provided in the resonant cavity. Absorption spectra of the anisotropic laser crystal comprise a ? polarization absorption spectrum and a ? polarization absorption spectrum. Each of the ? polarization absorption spectrum and the ? polarization absorption spectrum has a peak pump region and a left pump region and a right pump region arranged on either side of the peak pump region. Pump light outputted by diode-pump laser has a wavelength ? falling within the left pump region or the right pump region.
