NDB7675 diode

[Lifetime17]

Hi LPF,
Just need to know what your comments are on the 462nm / NDB7675/9mm diode .
#1 What would be the suggested setting fir long life
#2 What would the setting be to hit 470 NM

Here's some info :

Spectro-ing the new Nichia 1.4W "462nm-470nm" NDB7675

Just a quick thread on the spectro-ing results on the new Nichia 462nm-470nm 9mm 1.4W laser diode. First, for good measure, a spectro reading on my DPSS 473nm so that everyone can see that the spectro is properly calibrated: 473nm DPSS - test spectro reading (here) Now for the NDB7675... I'll...

I have one doing 465nm at 1770 mW driven at 1.8 amps with an X-Drive. I have another in my stock and plan to use a 2.4 amp SXD driver. I will let you know how that measures once I get it finished.

I also used a 1.8a X-drive and it's a very pretty blue, if I had a bunch of them I would drive some harder but I had also received 7875's not that long ago in place of 7675's so they may be difficult to find before long if they aren't already.

Anyone have some long term experience with running this diode 2.4A+?

I have heard of this diode being pushed to 2.8 amps. I wouldn't consider that a current for longevity, though. My plans for driving one at 2.4 amps is the limit of how far I am willing to try in the advancement of its WL. Each diode is different in that their wavelengths at, say 1.8 amps, differ. But, they all seem to increase in WL with current, even past the point where the power folds back.
