Yes it is coming to a focus, with an intensity of around 5MW/cm^2. Looks like I have found a great journal on this topic, and I will post a link below for anyone who stumbles upon this in future!

Looks like...
Thanks for your help.
1.The reason is that there will be a camera looking inside the tool, and if there is ionisation this will flare the camera image.
2.Yes, I am only trying to prove that under my conditions it will not occur. If it will occur, then I will have to design the enclosure...
Out of curiosity, may I ask why you have chosen to use this kind of approach? I am wondering what the benefit would be of using a air blaster rather than the simple scraper!
Hi guys,
I am currently doing a project which involves firing a class 4 laser into a small enclosure (200mmx200mm) and onto a target, which is to emit IR. I am trying to theoretically prove that there will be no ionization of the air (i.e. turn the air into plasma) inside the enclosure...
Thanks. I was just getting confused as I am trying to model a single pulse, and I felt that maybe it should be somewhat higher as this is a Class 4 laser.
It is for a dissertation, I am basically designing a tool to convert non-visible light from Class 4 lasers (of the specification I wrote...
Hi guys, I'm new to the forum, I'm a mechanical engineer but running a project a little outside my comfort zone which is to do with optics.
I am trying to calculate the power density of a pulsed Nd:YAG laser but am getting in a muddle with the Average and Peak powers. The project is to model...
