AI Article Synopsis
- Researchers have studied how a near-resonant laser beam creates orderly patterns in sodium vapor, both nearby and further away.
- A specific example of this is a honeycomb pattern observed in the far field, indicating a stable structure formed during laser interaction with the vapor.
- The experimental findings align well with theoretical predictions regarding the filamentation process involved in this pattern formation.
Article Abstract
We have observed transverse pattern formation leading to highly regular structures in both the near and far fields when a near-resonant laser beam propagates without feedback through an atomic sodium vapor. One example is a regular far-field honeycomb pattern, which results from the transformation of the laser beam within the vapor into a stable three-lobed structure with a uniform phase distribution and highly correlated power fluctuations. The predictions of a theoretical model of the filamentation process are in good agreement with these observations.
