The approach is biologically inspired and requires that the plasma be considered as an excitable medium. Using a soliton as a catalyzing agent would have the benefit of utilising a stable non-linear dynamic in a situation where non-linear behaviour of the plasma has been a significant obstacle in our efforts to achieve stable fusion. Please find attached a more detailed explanation of what I have in mind.
There is such an approach by Marco Borghesi et al.

Though I just have a quick look at the doc attached. I think this is indeed the way laser plasma acceleration works. The charge particles can be accelerated in the strong and and sharp potential field. Plasma based accelerators are now reality.
Have a look:

As long as Soliton waves does not have losses, then it would be a good way to generate pressure and low pressure in the plasma using strong sharp laser as said Joachim and Sanat but it does not heats the plasma.
