Laser device with a multi-mode optical waveguide comprising an optically active material |
摘要 |
The laser device has a multi-mode fiber (1) with an optically active material, having an end coupled to a single-mode fiber (2). The diameter of laser core (4) is 1.5 times as large as that of the core (6) of single-mode fiber. The core (6) is fitted bluntly on laser core such that the diameter of laser core is selected for making a multi-mode beam to emerge from uncoupling window (9) for photons, with the pumping of active material. The window is arranged at the other end of multi-mode fiber for preventing reflection of photons of lasing wavelength back into the multi-mode fiber. |
