For instance (I have not tested this because I do not have enough lasers and I know there are a lot more factors than wattage such as beam diameter but lets just say they are all the same and on infinity) if a 50mW 532nm can burn through a black garbage bag in lets say 1 of a second would a 200mW 532nm burn through in .25 of a second? and if a 1W 445nm lights a match in 2 seconds would a 1.2W light a match in 1.5 seconds? Also what about beam brightness (I know the divergence and beam diameter affects this too but lets just assume it is all the same) if a 5mW 532nm is 3 lumens would a 500mW 532nm be 300 lumens ? I may be a complete noob in this matter but I'm just wondering from those of you who have a laser collection large enough to test these things. My main reason for asking this is really is how much of a difference is there in burning power from a 500mW-1W-1.2W-1.5W-2W 445nm laser?
p.s. Would it be possible to take 100 1mW lasers and focus them all to one point and burn something the same as a 100mW laser?
