| 摘要 |
A monolithic laser cavity device includes an input mirror coating, a birefringent crystal quarter waveplate such as sapphire, a birefringent crystal gain medium such as neodymium-doped vanadate, a Type-II second-harmonic-generation crystal such as potassium titanyl phosphate, and an output mirror coating. The optical axes of the Type-II second-harmonic-generation crystal and birefringent crystal gain medium are aligned with each other and aligned 45° relative to the optical axis of the birefringent crystal quarter waveplate.
