Method | Advantage | Disadvantage |
|
Short cavity method | The most direct method, simple structure | Low power, low stability |
Etalon method | Simple structure can generate relatively high power | Introduce insertion loss, threshold dependent |
Traveling wave cavity method | | |
Nonplanar | Compact structure, strong stability | High processing requirements, limited tuning range |
Discrete ring | A variety of components can be inserted, with good mode selection effect | Complex structure |
Twisting cavity | Compact structure, easy to realize | Sensitive to polarization, greatly affected by thermal effects |
VBG method | Low-temperature influence, high stability | Low precision, limited operating spectral range |
Seed injection | High-power operation can be achieved | Seed light has a big impact on output |
Compound cavity method | Low temperature influence, high stability | Poor selection of single structure |
Nonlinear crystal method | Frequency conversion | Relay on the properties of nonlinear optical materials, quantum defect |
Multistructure combination | High precision | Complex structure, poor stability |
