Nice seen some 635nm diodes cooled with Nitrogen go to around 600nm but that is insane looked to drop about 100nm or more. Nice.

Is there a rating for the wavelength temperature shift on the datasheets somewhere?

Yea but he probably won't be popping too many baloons with a LED. Would be awesome if we could get these kind of shifts out of laser diodes.

https://www.youtube.com/watch?v=_AbQh1g_1ok

but wavelength shift isn't as dramatically as with an orange LED. There's also another one with some very detailed measurements... must see!

https://www.youtube.com/watch?v=0w4czym1FFg

Would be interesting to see how the blue or new greens ones behave.

Was looking for that video last night. Only found the one where planters was power testing with LN on the G71 with a peak of 1950mW. I knew that one where he turned it orange was somewhere and was what I was referring to in my first reply.

Default Re: Anyone tried this with a laser diode? (Huge wavelength shift)

To lase, the "active ingredient" must be able to emit the same energy as the photon when bumped with that photon of the wavelength that is already present and resonating. I think another way to say this is that the band gap of the "active ingredient" in the gain medium at that temperature has to be of a range that contains the light that is being spontaneously emitted. In other words, LD may be able to shift wavelength, but it might only have an LED'd output at those wavelengths.

Still, don't let that stop you. An experiment in the real world using materials that follow the laws of science is much more valid than some noob who doesn't have much of an understanding of these laws of science claiming that it will just emit incoherent light rather than lase.

but wavelength shift isn't as dramatically as with an orange LED. There's also another one with some very detailed measurements... must see!

Would be interesting to see how the blue or new greens ones behave.
He tested a 445nm and a 658nm diode as well as a 638nm diode, the P73.

The 445 died before it got too cold, and the 658 didn't do much of anything remarkable. Nothing that other diodes could do at room temp anyway. The 638 on the other hand, well, enjoy the video
