Default light waves and harmonics

dear mr. spock,
is there some harmonics between diode wavelength and amperage supplied thru driver? maybe in terms of fibonacci type ratios.
i dont know how to calculate such a harmonic amperage with a certain diode, but i wonder if such a thing exists?

i know that the higher the amperage the more stress it puts to the diode and it is likely to burn out faster with higher amperage.

i am thinking that if there is such a harmonics for amperage-diode relationships, it may be possible to have higher output as well as lifespan of a diode?

This forum is about lasers, not about incoherent sh*t

Sorry, but I can't make sense of what you're try to say, my guess would be you're looking for the current/wavelength relation of a laser diode, correct?

No. A laser diode will have one (or zero) wavelengths no matter the current.

I know of a least a few diodes that start single mode op to about 100mW of power and then become multimode, having multiple wavelength close to eachother. So there is a small dependency, but an important one for certain applications.

Yes, technically it's quite a few, but they're all within a nm of each other. For our intents and purposes, it's one wavelength.

They indeed don't go from red to green, that would've been nice
