"Lasers are light sources with well-defined and well-manageable properties, making them an ideal tool for scientific research. Nevertheless, at some points the inherent (quasi-) monochromaticity of lasers is a drawback. Using a convenient converting phosphor can produce a broad spectrum but also results in a loss of the desired laser properties, in particular the high degree of directionality. To generate true white light while retaining this directionality, one can resort to nonlinear effects like soliton formation."

2Physics.com publishes invited semipopular level articles on key developments
in various fields of Physics. Authors may submit semipopular level articles based on their own
research paper(s) published in refereed journal(s). Alternatively, they may consider sending a proposal
(one short paragraph) and a list of related publications before writing the full article. We will let you know our decision within a few days after we receive the proposal.
