Hey all -
So I have run into a bunch of difficulty lately trying to explain the relationship between power and "brightness" to people. Everyone wants to know whether x will be brighter than Y, whether 1w is twice as bright as 500mW, and all of those usual kinds of questions. I am finding myself to be... inarticulate trying to explain that these relationships are not always linear and proportional. Everyone is so BRAIN LOCKED on 50 is half of 100, etc. that I need some reinforcements. So, I am looking for some help... how would you - very simply - explain to someone who knows nothing about lasers all of the relationships between specification and effect?
I would also mention that much in the same way that Columbus and the Native Americans were best dinner pals right up until you got into middle school, the answer does not have to be totally technically accurate... that's where I am having them problem. It has to be understandable and any help would be most appreciated.
Thanks!
