| 英文摘要 | PURPOSE:To reduce speckle noises by projecting the other output beams of the semiconductor laser to a reflector of a vibrator and coupling return beams from the reflector with the semiconductor laser. CONSTITUTION:The piezo-electric vibrator 3 formed by gold, etc. having a high reflection factor and excellent conductivity is mounted at the reverse side to the optical fiber 7 of the semiconductor laser The output beams of the laser 1 oscillating at a single wavelength are projected to the reflector of the vibrator 3 through a lens 2. When the vibrator 3 is vibrated by an oscillation circuit 6, the variation of thickness is generated in the vibrator 3, a space between the reflector 4 and the laser 1 is changed periodically, and the laser 1 is oscillated at a stable wavelength. When the output beams of the laser 1 are combined with the optical fiber 7 through the lens 2, speckles are decreased, and modal noises are reduced. |
