  • Optical fiber laser coupler
    Patent number: 11846784
    Abstract: An optical fiber laser coupler, comprising a laser input optical cable, a laser shaping and coupling device, and a multi-beam-mode energy transmission fiber (205). The multi-beam-mode energy transmission fiber (205) comprises a circular fiber core (105) and annular fiber cores (106, 107), and each annular fiber core (106, 107) is coaxial with the circular fiber core (105). A fluorine-doped layer (109) is disposed between the circular fiber core (105) and the annular fiber core (106, 107), and the fluorine-doped layer (109) is also disposed between adjacent annular fiber cores (106, 107). An adjustable collimating lens group (203) and an adjustable focusing lens group (204) of the laser shaping and coupling device can horizontally move along a direction of a laser beam in a housing of the laser shaping and coupling device.
