| 英文摘要 | PURPOSE:To improve the coupling efficiency and the characteristic of a laser by arranging a double-refracting crystal lens, which has the optical axis in the direction of a TM light (having the magnetic vector vertical to the joint surface) of the exit light of the semiconductor laser, between the semiconductor laser and a Farady rotator. CONSTITUTION: A double-refracting crystal lens 10 which has the optical axis in the TM light direction of the exit light of a semiconductor laser 1 is arranged between the semiconductor laser 1 and a Farady rotator 2, and a single constant polarizing optical fiber 11 which has the principal axis in the direction to which the direction of a TE light (having the electric vector parallel with the joint surface) of the semiconductor laser 1 is rotated at 45 deg. and the Farady rotator 2 are coupled optically. |
