https://en.wikipedia.org/wiki/List_of_laser_types

Wavelengths of commercially available lasers. Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material

That's a better break down thank you.

Funny, I posted the same link yesterday.

It is, I've also seen the same link before many years ago. It has been updated a few but relatively the same elements and experiments used still.

Why is there no xray or gamma ray lasers?

Try reflecting X-rays or gamma rays and you will understand why.

Reflecting X-rays is exactly what's needed for EUV litography, Hiroo Kinoshita had to fight quite a bit to have his research taken seriously back in the days but it's the foundation to how EUV lithography works.

Uhh.. can you be more specific? I think it's possible to reflect xrays https://en.wikipedia.org/wiki/X-ray_reflectivity https://x-ray-optics.de/index.php/en/physics/reflection

This one photo doesn't include how to actually make a laser? Is that not something we need to know?

Pretty sure I went to a rave once where they used all of these.

Now if someone could make a similar power-wavelength chart for solid state diodes, that would be cool.
