Influence of Angle between Seed and Pump Beam on Brillouin Amplification |
| |
| Abstract: | Energy extraction efficiency, seed amplification factor, seed beam pulse width compression ratio and pump beam pulse width compression ratio versus angle between seed and pump beam at different energy ratio of seed to pump were experimentally investigated. When the angle between seed and pump was 1～2 mrad, energy extraction efficiency, seed amplification factor, seed pulse width compression ratio and pump pulse width compression ratio were changed very small. Stokes seed and pump beam could be misaligned by 1～2 mrad. |
