The discussion revolves around the term "laser field," specifically exploring its meaning and context within the realms of physics, particularly in relation to electromagnetic fields generated by lasers. Participants seek clarification on whether it refers to an electric field created by lasers and discuss its implications in areas like laser wakefield accelerators and strong field laser physics.
Participants generally agree that the term relates to electromagnetic fields generated by lasers, but there is disagreement on whether it should be restricted to pulsed lasers or if it encompasses all laser emissions.
The discussion highlights the need for clarity regarding the definitions and contexts in which the term "laser field" is used, as well as the potential for varying interpretations based on different applications in physics.
Misha Kuznetsov said:Hello,
I have encountered this term quite a few times, but I don't really understand what it means. Is it an electric field somehow created by a laser? Could somebody explain this to me?
I would say that that's actually a bit too restrictive. It is the EM field emanating from a laser, not necessarily pulsed, although I admit that contemporary work focuses on intense, pulsed lasers.e.bar.goum said:the term refers to the EM field generated by (generally very short) laser pulses.
