Laser transmission system |
摘要 |
A laser transmission system for transmitting laser beam to an optical fiber comprises a pulse laser oscillator unit, a beam guide unit having an optical condensing unit for condensing a pulse laser beam radiated from the pulse laser oscillator unit, an optical fiber unit for transmitting the pulse laser beam condensed by the optical fiber beam guide unit, and a device for reducing a coherence of the pulse laser beam provided for at least one of the pulse laser oscillator unit, the beam guide unit and the optical fiber unit. This coherence reducing device is for making substantially uniform distribution of laser beams at a beam entrance portion of the optical fiber unit and preventing the laser beams from focussing or converging on one point in the optical fiber unit. <IMAGE> |
