The experimental results show that the SA should be considered as a convex lens inside the cavity, whose position strongly improves output performance. A fourfold enhancement of the average output power is obtained, and the peak energy increases from 8.2 to 25 µJ. Theoretically, we calculate the thermal lens effect of the SA and the optimal position inside the cavity, which agree with the experimental results. | Source Title: | Applied Physics Express | URI: | https://scholarbank.nus.edu.sg/handle/10635/170653 | ISSN: | 1882-0778 1882-0786 |
