New Paper on Power Scaling of Lasers

Dr. Rüdiger Paschotta

Ref.: “Power scalability as a precise concept for the evaluation of laser architectures” in arXiv.org, see arXiv:0711.3987v1; encyclopedia article on power scaling of lasers

This week I published the above mentioned paper in the open-access repository arXiv.org. It is truly amazing that even though the term “power scaling” has been used for decades in the area of laser technology, this paper is the first (apart from my encyclopedia article) to give a solid definition of power scaling and scalability. (Anybody not believing this is kindly asked to provide me with a reference proving the opposite.) The motivation of that work is not only that it is very advisable to use clearly defined terms (rather than vague or even meaningless buzzwords) in science and technology, but also that serious thinking with that concept in mind can inspire a lot of useful thoughts, as common issues of high power lasers appear in a new light. In other areas of technology, such as computing, data storage, communications, and manufacturing, that lesson has been learned much earlier than in laser technology.

In very brief terms:

There are, of course, plenty of reasons to hate this paper:

Anyway, I hope the paper will be useful for many. An aspect which should help is the open-access nature of the arXiv repository.
