Is there such thing diode ageing?

Like, if I use my laser a lot, sometimes not according to its duty cycle, then the diode can weaken and the output power will drop?

If there is such a phenomenon, does it vary from one wavelength to another?
:thanks:

I don't think that lifetime is wavelength dependent, even if you're operating outside of the diode's specs. Most laser diodes are rated to 10,000+ hours as long as you abide by the datasheet specifications. Using a laser diode under bad conditions until it gets too hot WILL shorten the life, but it's nearly impossible to say by how much. It varies from individual diode to diode.

Thanks for your reply.

My question is, whether using a laser diode under bad conditions until it gets too hot WILL cause it to lose power output? Or it will perform the same but just will die sooner?

I know that it will shorten the life of the diode, but till it dies, will it perform as usual?
:thanks:
