 From how far away could a Viasho 1 watt 532nm Green lab laser pop a balloon?

Im just curious, as a fun question what do you guys think. By unfocused I mean just right out of the unit without focusing lenses like they use with rubys and yags to blow holes through razor blades. I have a 150mw 532nm unit and she'll pop dark balloons within maybe 5-6 feet but it takes a bit. I've seen a YouTube video of a guy using a 1 watt Viasho Lab Unit to almost instantly light a magazine on fire, I mean bursting into flames within 3 seconds or so! And the beam is very visible in plain daylight. So would that pop balloon across a football field say at this power level maybe? They regularly test at 1.4 watts those 1 watt viasho lab units it seems. Viasho goes way higher with their modules but I am curious with the 1 watt "baby"... Hahaaaa...

It depends completely on the focus/spot size, the 1W blue diode lasers are 100% underwhelming as far as power density goes. With a 3x5mm beam, the burning isnt as much of a scale up as I expected from my 90mW green which had a pretty fine pinpoint beam.
Find me a 1W laser with a <0.5mm x 0.5mm beam thats well collimated, and now we're talking business.
Given that youre talking about a lab quality unit, I would expect the beam quality to be much better however.
