| 英文摘要 | PURPOSE:To improve the total coupling efficiency by performing multiplexing which utilizes the wavelength division of a dichroic mirror first and then making laser light in a uniform vibration direction incident on a polarization beam splitter PBS. CONSTITUTION:Laser light beams 1a and 2a emitted by 1st and 2nd semiconductor lasers 1 and 2 are made incident on a 1st dichroic mirror 6a and laser light beams 3a and 4a emitted by 3rd and 4th semiconductor lasers 3 and 4 are made incident on a 2nd dichroic mirror 6b. Thus, the four laser beams from the four semiconductors are converted into two light beams, which are made incident on the PBS 5 and multiplexed into one beam. Consequently, the total coupling efficiency when the laser beams are coupled with an optical fiber is improved. |
