Lightbulb Home-Made Laser Diode

I was just wandering if it is possible to make your own laser diode for under $50





Sorry for this off topic note but how do you add a signature here?

Thank for the sig advice
But can you then explain how a laser diode works so maby I can figure it out

If you are good at reflow work and have a laser die you can, but it's still incredibly difficult.

A reflow station is $200 or so on eBay, and I'm not sure where to find a laser die anymore, with Chris no longer selling them.

I am asking because I noticed that when I shine my green laser at my lava lamp the beam inside turns orange and I thought I could some how make an adapterfor my laser to shoot an orange beam

the beam is orange only when in your lava lamp (by fluorescence)... how will this work unless u fill your whole room with lava lamp fluid?

@hugo999999 I was thinking that if I made a diode with this fluid in it it might slow the wavelength of the light enough to make a yellow orang laser

Hmmm, read this: What a laser diode is and this: nonlinear optics and this: Fluorescence. After that think again about doing it yourself a laser diode.

What if you try a test 1st? Find a small glass hollow flat sided container. Glue the glass together if you need or shop around for something glass, hollow, that has 2 flat sides.
Next, fill the space with the lava lamp fluid. Now fire your laser through it and see what color comes out the other side on the wall. Then decide it you want to spend all that money on equipment.

Default Re: Home-Made Laser Diode

What all these guys are saying , in short, is :

NO!

If it were only that simple...

Sorry, but making your own laser diode is next to impossible. It requires soldering a small (0.5 x0.5 x0.005 mm small) laser die to a brass base , then making an electronic connection.

You can't do it.

For $50, you can buy an awsome first started kit for PHR 100mW 405nm build, or have very nice green laser pen build.

Leave exotic laser diodes to researchers. They need to invent them first.

The color that comes out is green but dispersed. I tried to shine the light through some crystals that resemble the fluid and the crystal glows green
