My gut tells me it's a Ushio HL63520HD that's had a FAC added to it, hence the price increase over the regular diode. Both the Ushio and the LaserTree data sheets show the same double diode in the spec sheet for the pin out. For multi beam lasers I quite like the Mitsubishi line up.

The 2.4W is a double beam diode, I believe the original manufacturer is Ushio

That depends on the diode and driver you plan on using. If you are doing a A140 diode you can use something like an ACS1500SE because it can supply the forward voltage for the diode and supply ~1A of current even when being driven on a single cell. If you went with something like a NUBM44 you...

Those just aren't up to the task then unfortunately. I ran the test again with the same two glasses this time with 125W's of blue The amount of blue coming through these glasses is still too bright to look at Much better! No blue and I can still see where the dot is on the concrete

This is 7W of blue light on a white wall with no glasses, obviously don't look at this it will damage your eyes This is that same dot as seen through glasses with an OD rating too low for the laser in use. The laser's blue wavelength is making it through the glasses which is why the dot...

I'd be willing to bet those aren't true OD6 glasses, I'm sure they are nice glasses but probably not OD6. I have a set of glasses (unknown rating) that I use with my 125W NUBM37 laser and the dot is just barely visible, only bright enough to let me know what its pointed at, assuming what I'm...

Yeah the news really rocked my world, he was one of a handful of names I remember having such a positive influence in the laser community

I do miss that big guy, I'm sure he would have loved it. For anyone that doesn't know Jayrob passed away from pancreatic cancer back in November of 2021. His work with a lathe was legendary and he was always pushing the bounds of what seemed physically possible.

I'm fairly certain the best you can get in 510nm are ~35mW diodes (all single mode) but if you go 520nm there has been a bit more development. The Sharp GH0523AD2G claims 300mW with divergence specs that look like single mode. I haven't tried this diode so that's just going off the spec sheet.

I'm not sure as I haven't tried either of them but I would guess the older NUBM0C is more similar to the NUBM07 while the newer NUBM0G is closer to the JLD470. But that's just speculation

JLD470 is on top and NUBM07 is on the bottom, both with can, G-ball adapter and G8. At 35ft the JLD470 is 88mm wide and the NUBM07 is 41mm wide. In the 30 or so secs it took to get the lasers set and take the measurements the JLD470 burned through 3 layers of the black felt

Both lasers are running the same lens setup with a G-Ball adapter and G8 so I can do a comparison test later today. The new diode definitely has more divergence than the NUBM07, I'd be willing to bet if it were decanned the new diode would be up there in the NUBM44 territory.

The energy density in the beam is wild, focused down to a spot it will melt concrete haha. The lens attachment just slides onto the end of the frame and is held on by friction for a quick and easy install and removal. Punches through soda cans like nothing, just rotate the can and it'll...
