hello everyone 2 days ago i received my nubm49 diode for testing and the results aren't that good as we have better choices than this diode. first of all the divergence out the gball is like flashlight exactly like nubm42 i have tested in my previous post,while i could get a good output out of...

today i found some time to test out the new nubm42 diode i received and i have to say i found some interesting results. there will be not a lot of photos but i'll share the differences i found out compared to other diodes. nubm42 is very identical to the nubm08 and the power test is almost the...

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...

i just found this on ebay today and i think its real as its listed from a trusted seller. https://www.ebay.com/itm/to9-tin-pin-nichia-525nm-1w-high-power-laser-diode-w-ball-lens/263691115473 on the discription has both names ndg525 and nugm525 so i don't know witch is true.(i think the nugm525...

finally got some time to make a complete thread about the newest diode on our laser world sharp GH04850B2G the chameleon light as i named it because i can't tell what color really is as its always changing on my eyes depending the enviroment and other lights. i was planning to upload images...

hello everyone today one of my 1st builds i ever made when i started this hobby died-zombified, althought it was an old build it had very low hours runtime(im guessing somewhere 5 hours). today i turned it on and noticed it wasn't that bright and after checking the batteries i unfocused the...

hello everyone its been some time since i posted on the forum and i have made this build over a month ago and i wanted to share it :beer: It is a kind of budget build but it feels very nice on the hand and i love it. the host was originally 2x AA batteries and after a bit of sanding on the...

i just saw this diode on ebay, it is an osram diode rated at 90mw,the seller has a messed up diode package as it list this both as a 5.6 and 3.8mm diode but it has a 480ma working current which looks very promising if it is a single mode. has anyone tested this...

i just finished my smaller blue laser in my collection as all my blues are generally big. the host is 1x18650 battery, i used a boost driver and everything works nice,the divergence is acceptable on this multimode diode even with a G2 lens. also i just got my new phone(oneplus 3) and i was...

i saw a listing on ebay about a new nubm41 diode and seller claims that is indentical to the nubm05 but it supposed to have output close to nubm44-47 and nubm06.has anyone seen this diode before? :wave...

hello everyone i had a unique idea about 4 months ago to make a handheld tec-cooled red laser,it took that long to think,draw and finally gather all the stuff i needed to complete it. its almost ready except some visual fixes so i have to share it with you :) i uploaded the images on the forum...

hello everyone today i came to a weird find on ebay.this is supposed to be a 905nm 4w pulsed diode in 5.6mm package. :eek: another thing that i saw is that on the title says 'A series' and if you read the description it mentions this: Beam Quality: - A series mean that the chip will produce a...

hello everyone around 2 months ago i bought 3 of those 1dollar 5-20mw 405nm diodes that ebay has, there was no info at all,no datasheet or any recommended current so first i had to find the pinout. after some testing i found that those are case negative,i made a power test with my psu and things...

hello everyone today i was searching for diodes on google and i saw this diode: LDX-3125-520-FC: 520nm Fiber Coupled Laser Diode - Solid State Lasers and Laser Diodes from RPMC Lasers Inc i dont know exactly the differences with the normal diodes but this has a weird can(to fit a fiber i...

hello everyone yesterday i was testing a NUBM08 diode and i accidently the can popped out while i was removing the diode from the heatsink,we all know how this diodes tend to degrade after some time if you take the can off but this weird idea and question came to my mind,what will happen if i...

hello everyone i just want to let you know that recently bought an ndb7675 from ebay (link at the button) and i just received it,first thing i noticed was that it didnt had the extra text on the back of the diode that the 7675's normally have. after testing im 100% sure that this diode is...

hello everyone today i managed to rebuild my old 405nm bdr209 laser with an s06j diode.the build is very budget and not so awesome made like most people on the forum do. the diode pressed used some heatshrink put the housing inside the heatsink and assembled them all to the old...

hello everyone, recently i bought a 445nm 120mw module from ebay,it is a single mode so first thing that came to my mind was that it uses an Osram PLT5 diode and also was the reason i bought it. when i recieved it and powered it was definetly a nice singe mode beam and the output was true...

Re: new Sharp 495nm diode(after testing it confirmed just 488nm) hello everybody good news for all of us,i just found a new diode with a very rare and awesome wavelengh! Sharp 495nm 55mW Laser Diode/5.6mm/Brand new/1 pcs i guess its real as it was the previous new 505nm and 473 diodes :)

i found this Sharp 505nm 35mW Green Laser Diode/Brand new | eBay it listed as sharp 35mw 505nm,anyone have tried the 505nm wavelengh?i couldnt find any info on this diode or wavelengh so im curious if anyone have tested it or already have it in a build
