Hey All,
NUBM07E TEST
Here is a Power,Wavelength and a couple beam shots of the New 465nm NUBM07 Laser diode.
This is an Awesome diode with the highest wavelength we have seen so far stable with the highest power. I'd say its a "Sky Blue" diode running it at the Max Current that we typically run diodes at today. These Peak Higher then the 462nm diodes thats for sure.
This diode hits 470nm No problem. I bet we may even see some get closer to 480nm Before roll back.:wave:
Its Rated for 2.3A at 2.9W with MAX current of 3.5A
Pictures:
Here is the Datasheet:
The back of the diode. It says 465 on it. (The diode was scratched when i got it like that but you can still make it out so its for sure a new diode we have never seen before)
Beam Specs compared to the NUBM41/44/05T:
Beam size near field is ~1.85mm x 3.2mm for the NUBM07E @ 3.5A. This measurement was taken at 10" from the actual G-lens. I used a dichroic mirror that passes the blue @ a 45 and measured the back reflection waste beam that comes off it. The image above is not spatial filtered. But just regular beams with G lenses. As you can see much better.
Power Tests are done with a G lens.
Here is a Graph for those that want to skip the images:
Threshold:
Nearly 5W of 470nm+ Clean. Epic.:wave:
It is to be noted that the power test was done at a more realistic temp for Handhelds of ~30C-40C. If you are curious at 25C expect ~500mW more power in the images.
Wavelength charts:
Recommended Typical Current:
Recommend MAX Current:
Right before Role back at this Temp:
Right after roll back if your willing to push it for Higher WL with risk of diode damage:
Again it is to be Noted and payed attention that the ROLLBACK will be at a different point if your diode is at a different Temp then what i show. Pretty much anything above 5A is not recommended IMO and with 4.5A being the MAX... The typical roll back i noticed is around 5.5A-5.8A at 25C. So if your experimenting to get that extra 1 or 2nm out of the diode just pay attention. I do know that at least for this diode it wont die up to 5.8A... Past that i do not know. Dint want to push it until i get more diodes in.
Here are a couple Quick Videos:
^With a Glimpse of the next diode i will be posting.
All in all this is a World Breaking diode. 470nm+ with a tighter beam profile then the other NUBMXX diodes give is Just plain awesome. With the Higher Wavelength that these give at a much higher power then the 462nm diodes its just something we have not seen yet. These are as close as we got to 473nm diodes and id say we are kissing right at the edge.
These are Not only brighter but also tighter beam then what we have seen in 3W+ diodes. So i think these would be a Great blue "sky blue?" addition for combining and maybe even a better option. What i can say is these are a much sharper line/dot then the other NUBMXX diodes and ill try to show that later. Very Similar to M140 when it comes to sharpness.... Ill be correcting this beam a little later and will post an update. I got too many different new diodes in all at once "like 8" to test and just been overloaded. So the more intense beam testing has been lagging but iam getting there.
More to come......
Part2: ADDED 2 BEAM VIDEOS
Note the NUBM07E is on the top & the 44 is on the bottom. It is also to be noted that the 44 is flipped upside down by mistake so that all the extra strips are on the top side of the image beam rather then the bottom. Doesnt matter but i'd like that to be clear as if the diode was right side up you would see all the extra strips mostly on the bottom. Both diodes where at 3.5A so thats pretty much full power.
Cheers:beer:
Thanks For Looking.!!!
Keep on Lazing.....
