| 摘要 |
This invention discloses to a multi-stage optical isolator having a large centrally disposed birefringent crystal and two smaller crystals sized to separate in a polarization dependent manner into sub-beams and combine light that is separated into sub-beams at an output end thereof. By providing a single large crystal centrally disposed, less alignment is required due to fewer alignment critical components being required. Furthermore, the isolator in accordance with this invention is well suited to high-power applications.
