Abstract We have studied the transient behavior of thc self-pumped phase conjugation when the incident beam is below the saturation intensity. We found that, when the incident beam intensity is changed abruptly, the intensity of the conjugate beam always decreases at first and then gradually increases to its stable value. This is due to the fact that the positions of the two coupled interaction regions are changed.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
