EvilmonkeyzDesignz | What's inside a laser diode? #laser @EvilmonkeyzDesignz | Uploaded March 2024 | Updated October 2024, 13 minutes ago.
Safety warning: definitely don't look at a laser with your eyes. Always wear laser glasses to protect your eyes, especially when working with lasers that emit light outside of the visible-to-humans spectrum. My phone was always in-between the laser and my eyes during the filming of this video, and I never put my eyes up to the microscope while the laser was underneath it.

I removed this is the laser diode from an HFCT 5205A fiber optic transceiver . Here you can see that the laser module is made up of two main parts, the laser diode and a photodiode mounted behind it. To my knowledge, the photodiode here is used to tune the output of the laser diode.

Like I stated in the video, I'm not 100% sure we are seeing just the laser in this video. The laser should emit at 1300nm, but my phone can still see it. My phone can see IR light, bit I don't know how big the wavelength can get before it doesn't see anything. This could be light before the the laser actually starts lasering, I just can't say for sure. I was also surprised that the light exited from the location that it did, but if I knew more about laser diodes, maybe it would make more sense.

The Wikipedia page on lasers has a lot of good information and links to further reading material, much of which goes right over my head š
