Okay I'm building a Mitsubishi 150 milliwatt laser the diode outputs less than expected light but it still doesn't qualify as burned is my diode dead or my driver toast.
Yea just found out never buying again from ebay ill buy from dtr instead https://sites.google.com/site/dtrslasershop/home/diodes/oclaro-hl6388mg-637nm-250mw-laser-diodeReally can't tell as the pic's are blurry but it does look the one emitter wire has burnt off the pole.
Also just to add that a red 650nm laser beam even at 150mw is not bright. A 650nm beam is about 5% as bright as a green 532.
For about $3 more it's really something to think about. Still a 637 or 638nm diode will need to be run hard for a visible beam..Hi
The Mitsu 500 diodes can do over 1W easy and
Last. They are very tough

Ik Rich but sadly I was under the impression that red diodes need 5+ volts so I fried my Mitsubishi 150mw one is it possible to bring it back by soldering the tiny broken wire?Hi

No, that's not possible. Once it is toast it is toast.
Ok I'll just hook it up to 25 v for its final goodbye ( my 2-25 volts homemade driver https://laserpointerforums.com/threads/help-me-choose-the-right-driver.104475/ scroll all the way to the bottom)No, that's not possible. Once it is toast it is toast.
Hey Rich the driver performs very well and I also don't have the 30+14 USD for shipping. It was my fault for burning the diode my driver outputs a constant voltage of 2-25v and a Constant current of 0-2Amps(measured with a very good multimeter. It was my fault bc I did not look at the spreadsheet and fed the diode 4,5 or more volts. A lesson learned would you say. but still, I will buy the sharp 700mw red laser diode from dtr when I have the money.Hi, Just buy the driver from DTR I use the flex drive V5 for the Mitsu 500 and they just keep going and lasting. By purchasing the right driver you will save on diodes . Do not forget your ESD protection and safety glasses,

Rich it's ok don't be sorry. I am located in Greece and I do not really need an other driver as I am not really concerned about size and testing it on a burned mitsu 150mw it performs well. https://ibb.co/kyxgvb3Hi,
ok the shipping depends were you are from on the continent . I must have missed that sorry.
Rich
Sure Rich as soon as I get my 80mw green or, my m140 form eBay will provide you with some beam shots.Hi, Ok I hope it all works out for you , looking forward to some beam shots.
