Depends what you aim to cut or engrave. Best will be Diode laser, as otherwise you will need tubes and optics. You will need a controller that supports laser control probably analogue control via voltage variation and software that could do that.

You will need a screen to protect the machine from accidental glance, good quality laser goggles at the spectrum of your laser, a chiller ,compressor and air absorber and filter.


On a bed size like yours is not worth to invest in Yag laser. As for the same money you can have a separate laser machine. The only thing worth the game is say real 2w diode and analogue controller. Or 2x2w . You could engrave stuff like with Picengrave. I have a setip for this which i never had the time to implement, if interested i could sell. PM me.

So if you want to cut sth is not worth it.
