CD Player Laser Deterioration

Propeller Head Plaza

Technical and scientific discussion of amps, cables and other topics.

A couple of decades ago, I was a sales rep for laser-based measurement equipment. We in the business "knew" that the half-life of a laser diode was about nine years.

My Denon CD player is starting to falter, and I'm wondering whether I can presume (as I do now) that the laser is used up and it's time for a new one. Is this a process that anyone has gone through? I mean, many of you just use some of your lunch money to buy a new player, but I like this one and I hate to see all this hardware go into the dumpster just for a little bitty diode.

Informed comments and shared experiences anyone?

Thanky.
