Changes in c, l and λ affect self-focusing characteristics of RAVB.
| Modulation parameter | c | l | λ | |
|---|---|---|---|---|
| Change range | 4–8 | 1–7 | 100 nm–380 nm | 380 nm–780 nm |
| Focus depth | 8 cm–41 cm | 35 cm–46 cm | 196 cm–52 cm | 52 cm–35 cm |
| Size of focus spot | Decreased | Increased | Invary | Invary |
| Uniformity of light intensity in the focus spot | Uniform | Non-uniform | Uniform | Uniform |
| Focus peak intensity | Increased by ~50 times | Basically unchanged | Increased by ~1.2 times | Increased by ~2.2 times |
