| 英文摘要 | PURPOSE:To reduce speckle noises by inserting an electrooptical element between the semiconductor laser and a reflector and coupling beams from the other side of the semiconductor laser with the optical fiber. CONSTITUTION:The output beams to the reverse side to the optical fiber 5 of the semiconductor laser 1 are coupled with the reflector 4 through a lens 2 and the electrooptical element 3. The beams from the laser 1 pass through the element 3 twice by the reflector 4, and recombined with the laser 1 while the phase is changed only by pi. Consequently, a high frequency power supply circuit 3c is added to the element 3, a laser oscillating at a single wavelength can be oscillated at a large number of stable wavelengths. Accordingly, the speckle noises are reduced when the output beams are combined with the optical fiber 5 through the lens 2 after said operation. |
