I put a copy of this image into the commons. It is my own work, and was created just before uploading, after I surfed the net for N2 lasers, after our N2-laser failed to pump another laser.
I, the creator of this work, hereby release it into the public domain. This applies worldwide.
In case this is not legally possible,
I grant any entity the right to use this work for any purpose, without any conditions, unless such conditions are required by law.
