Re: Sell!!! 525nm custom build nice build and very impressive host,i think you will have a problem with the decanned diode,my nugm01 is decanned also and i have it around 3 months without signs of degradation.seems like the problem is mostly on the blue diodes. btw this diode is 520nm so why...

a can could be extracted from the cheapest 9mm diode even by destroying the diode or simple extracting it,a tiny bit of thermal silicon could be used to secure it on the new diode,thermal silicon has strong hold and don't leave any residue to to optics or the emmiter.

nice,im happy that worked out for you,im waiting 1 nubm42 also and i'll do a power testing to see if it is any different from the nubm08. yeah this method mostly helps out when we have a unique diode like the nubm07 or the new nugm03 that is 525nm,on those options we don't have any alternate...

yeap i was about to say the same thing that all nubmxx have build in antistatic protection,i don't have access and experience with any kind of gases so i can't help your ideas,someone has to try somethink like this by himself like i did with the focusing gball's and share his results

as everyone said your problem is either your crap batteries or your driver has bad heatsinking. if you end up looking for better batteries i would suggest those pkcells as i call them best value for money,i have 16340's and 18350's and after testing all of them are above rated capacity while the...

i cut it in lines and each piece was coming out very easy,im not sure if the tape is good idea cause it can easily melt from the rising temperature on the can while cutting it or leave some residue on the lens. my cutting method was like this

yeap this is how i removed mine but i accidentally touched the disk to the lens and made a very small scratch but i can confirm that this method works great,just need to be careful

i don't think that the degraded diodes can be restored because they don't act like something blocking the output,testing my degraded nubm08 i found out that the threshold of the diode to start lazing moved to 1.2A(was 450ma new) and if i push anything higher that 4.1A it leds just like to be...

its easy to just think that we can fill those diodes with gas but i can only imagine that as an experiment and nowhere cheap way that all community hobbyist could buy, also there are some other problems that will be expected as the evailability of the new cans that we need(to seal back the...

interesting thought about the final gball diode,you must use the lens of the nubm05,06 or 07 that have longer focal length,the 08's are definetly shorter focal length and you can see that from the shorter can that those diodes have.i had an extracted gball lens from nugm01 diode that should be...

RedCowboy i see you have plenty of extracted gballs (you lost many diodes i guess) i only have 2 diodes decanned and even those accidentally happend while pressing them. one is a nubm08 that now it does 2.5A 300mw and the other is a nugm01 that still going strong in full power. i don't think...

yeah this was the main reason for the project,to make gball diodes more usable on our hobby. could be a bit more,i can't remember exactly the the raw Gball reading,it was somewhere to 6-6.5w.still its usable with a pair of G2's if someone don't want that amount of lost power it will still have...

Of cource there are power loses but this has only to do with each type of lens,as RedCowboy mentioned 3 element lenses have big lost power,i have not metered the outputs on the testing but i already own a nubm08 build that does around 6w out of the gball and after this method with 1 G2 and a 3...

hello everyone i decided to make a small and quick tutorial about all the latest diodes with gballs and how to properly focus them because i have read alot of comments from members that don't even buy or want any gball diode because tend to degrade after deccaning,well you don't have to deccan...

well those are good news as all of the low powered single mode sharp diodes that we had till now could safely pushed up to 2 or even 3 times above the rated power. who wouldn't like a great single mode 300mw 520nm laser? :)

i have tried only with a nubm08 diode and this certain diode had good focus but i couldn't stand the awful divergence as you already know how much line it is and thats why i made this focusing mechanism to just make it focusable with lower divergence and gball intact.you must try a beam expander...

if it is a blue diode i suggest to nor deccan it as it will not live long(i got a green deccaned and 2 months laser still it has the full power ). i did the experiment with the G2 and 3 element, you can check the post here...

awesome build and very small host for that power,1w green is a stunning wavelength and power to have.enjoy your most visible laser :)

well maybe you are right about the nub/nug diodes but this is totally normal for the the osram pltb450,i just fired my pltb450 build running on 1,2-1,3A that works great and this is the raw output,it also have small lines that camera doesn't pick it well.i have tested 3 osram pltb450 brand new...

this diode is definitely a PLTB450B as for the weird output on the left side this is normal and how a PLTB450B raw output should look like.as for the completely clean output you looking for its not gonna happen with those multimode diodes except if you mask the output
