    Ok, but somehow they manage put this 50W beam to fiber witch is 100um diameter. How they do that? If I put YAG crystal to beam path dose this work. I know there is about 70% power loss but at least beam shape is ok? I learned that 808nm will be absorbed in YAG quite short distance. So I think...
