Have you tested to see if there's any IR in your beam ?
How about looking at your 10W 532 beam next to a 1W 520nm in a dark room with light fog/smoke........you can burn a litle cardboard and mix a very light amount of smoke with room air to show the beam well, I'm curious how much brighter 10w is compared to 1W ..........supposedly twice the power is half again as bright so 4W should look twice as bright as 1W and 10W should " look " somewhere on the order of 2.5 - 3 times as bright, what is your opinion ?
I'd love to have that 473 nm if you can find a way to get it to me with the postal situation going on right now.
Here's a video I took yesterday (my yesterday in Qatar) showing a 1.10 watt DPSS beam next to the 10 watt DPSS beam at different power levels as well as comparing the power density to burn through plastic for each beam. Even though the big laser was set to twice the output power at 2.25 watts, the 1.10 watt laser with its much smaller diameter beam would burn just as deep, just as quickly.
Robert, I didn't use smoke to make the beams appear, I moved to the end and took the video looking back at the source I could see both beams at the lower power output settings, so didn't need smoke.
Have you set a lens in front of it yet to get a tight waist, it should cut popcycle sticks.......when I focus my multi beam arrays and burn wood it instantly produces the most awesome jet of flame like a blow torch, must be the expanding gases.
I built some screw adjustable mounts so I can paint a dot on tree trunks on the creek bank across a wide wash through the woods about 400-600 yards away ( winter months and when the foliage is absent ) and I set up my spotting scope to zoom in on it, dusk and early morning is a good time when there's enough daylight to use my scope but the spot still shows up well, it's very interesting what looks like a tiny round spot that's just visible to our naked eyes when you zoom in on it from a distance....anyway the beam quality is something dpss can deliver @ multi watt levels that visible direct diodes can't easily match yet, I do enjoy my low power 520, 505, 488 diodes with a G8 and beam expander, actually the G3 works well too but dpss is hard to beat. I would like to have a nice quality multi watt dpss to experiment with at distance, one with a true TEM00 Gaussian beam........how far have you ever transmitted data on a visible laser beam ?
I never got the digital laser network going, took another job and that ended, boxed away. Analog though, a few hundred feet, but unless carrier shift modulated using BPSK with two audio frequencies, as I used while in the military for teletype 45 years ago which could transmit data using analog tones, I never had my circuitry developed to do digital.
The ten watt DPSS is near TEM00, it has an oval shaped beam output and not completely clean either, but it's as close as I can get, or rather, will allow myself to afford and it was on sale. I'd love to have a 589 nm DPSS next, but for the amount of power, wow, those are expensive.
I always like to see photographs of what you are doing whether beamshots from your side window into your burn pit or in the basement, so please keep them coming.
I'd like to do some night beam shots, but cannot do so in the middle of the city in an apartment complex. If I find I can legally use it out in the desert, I suppose I could rent a generator and go try it. But even then, I wouldn't keep a beam up for very long, I don't want to invite anyone to come find out who is doing that.
