Shout out to DTR, Thanks for another great diode. :beer:
The NUBM44 is a workhorse diode that lasts and lasts and is my favorite, all it needs it that gargantuan divergence corrected a little bit, then add a sanwu 3X BE and you will have a lot of fun, the moisture in wet green leaves explodes and fizzles with such rewarding sounds, and dry leaves across the yard release their fire and smoke that holds them together....yes leaves are really made out of ashes, its just the smoke and fire that's holding the ashes together.
Please remember SAFETY FIRST, always protect your eyes and know your backstop, a moments laps in safety can cause a lifetime of disability, don't let it happen.
OK so even a simpleton as myself with not much tools can get some fun out of these amazing diodes, here's how.
Next will be adding a sanwu 3X, everyone should get one, they are fantastic.
Also the top cover plate and the front cover plate that the 3X BE will mount to, run out can be adjusted with set screws in the corners if you need to, but covering your optics is important, dust, smoke basically every contaminant will become a problem in time..... but not if you cover your optics and seal the output with a sanwu BE. YES the fantastic BE adds protection as well, it really is a win win.

LOL laserbee, as Al Bundy's father once said: There's rarely a mix up that a sander cant fix up.

EDIT : I said perpendicular, I meant parallel, your diode should be focused to a horizontal line centered at a distant point, then center your lenses as you set them, I use UV glue and set the lenses with a couple little steel files while it's running of course, then I use a 365nm FL and 405nm laser to cure the UV glue.
I went to Munich, Germany a few months ago and it was amazing. I highly recommend going there if you're into castle's, art, sausage, schnitzel, huhn, and beer.
