NDG7475 1W+ 520nm Laser Diode (Real 1W @ 1.5A) AKA NDG7K75 NDG7475T

Description

NDG7475 1W+ 520nm Green Laser Diode
Max Suggested Current 2.2A
For more info see the community testing thread on the LPF forum.
These diodes have also been called NDG7K75 which is not a production model number and NDG7475T which (T) was the Test Sample batches first run of the actual production while they are still in development. All the modified and faked datasheets are based on a leaked test sample sheet. No one will have actual (T) batch diodes to sell. Just more misinformation that has been allowed to run rampant here on eBay.
These are real 1W+ NDG7475 not the NDG7575(NDG700) which has always been a 700mW rated diode till recently sellers started calling them 1W with as usual a fake datasheet showing it as a 1W but stating a higher max and nominal current basically meaning overdrive it to get to 1W which is less efficient, generates more heat and will reduce the life of the diode.
Genuine NDG7475 diodes will reach 1W with 1.5A-1.6A as shown in the testing below and when pushed their max can hit around 1.4W.  NDG7575(NDG700) sold as 1W NDG7475 will do 1W but it is over the nominal drive current of 1.5A to 1.7A-1.8A and will top out around 1.1W when pushed.
I also have options for this diode in several sized high grade 99.9% pure C1100 copper diode modules, In the modules with a glass collimating lens or a full module with lens and incorporated laser driver for a ready drop in module for your end project. Check out these listings.
NDG7475 Options
Diode should be properly mounted via the base to a heatsink for thermal stability and use of a actual laser driver providing constant current that is  properly applied and filtered by the driver of no more than 2.2A. If what you are using has the ability to limit voltage it is not a laser driver and even if it is a pure current regulating source might be only designed to operate withing the stress tolerances of LED's causing a great abuse when used with laser diodes. Shortening the life of the diode considerably if not just a COD death right away. A improper power source without proper inrush and over/under shoot suppression can damage the diode in a event that happens in millisecond time scales meaning it would happen faster than can be perceived by the human eye and no signs of what just happened as many that have had this happen think there would have to be a flash of light produced from the lasing cavity that would be seen before going open circuit.
