Is it safe to breast feed after getting laser tattoo removal?

I was told it was safe to get tattoo removal while breast feeding by the facility who provided the treatment. Now after I have received the tattoo removal I hear it is unsafe. Is there any clarity you can offer about weather I can feed my son? I really do. It want to feed hi. Anything other then breast milk but I am very worried I will harm him. Any clarity you can bring to me would be greatly appreciated.
