Investigation of thermally induced birefringence simultaneously compensated by both an intra-cavity 900 rotator and an intra-cavity quarter-wave plate

摘要

The effect of thermally induced birefringence in a Nd:YAG rod geometry resonator, which is simultaneously compensated by both an intra-cavity 90 degrees rotator and an intra-cavity quarter-wave plate, is experimentally investigated. The experimental investigation shows that, compared to the resonator with thermally induced birefringence solo compensated by an intra-cavity 90 degrees rotator or an intra-cavity quarter-wave plate, the output power from the resonator simultaneously compensated by both an intracavity 90 degrees rotator and an intra-cavity quarter-wave plate increases more than 16%, and the depolarization loss decreases more than 67%. Compared to any compensation, the depolarization loss decreases about 85%. (C) 2015 Elsevier GmbH. All rights reserved.
