Information Unlimited still publishes good designs for lasers and masers
of the home grown variety, and sells hard to get parts like HV
capacitors and diodes, etc.

There are, I think, FCC regulations on classification of lasers and
masers based on power output, but nothing I know of which restricts who
can build them.

The National Firearms Act of 1934 applies to any class II or III weapon
(sawed off shotguns, machine guns, etc) which applies, respectively, $5
and $200 taxes on the sale of such weapons. Technically it doesn't apply
to a person constructing their own personal weapon that fits in those
categories, but if you sell it to someone, you are breaking the law,
since the so-called Firearms Ownership Protection Act of 1986 banned the
sale of post-1986 manufactured Class II and III weapons to anyone
without a Federal Firearms License (Class III), and bans the sale BY
anyone without a class III manufacturers license of such devices.
"selling" under the NFA and FOPA is more than just exchanging for money.
If you die and leave it to a wife or other relative or friend, that is
considered a 'transfer' under the law, and comes under ATF jurisdiction.
If the person receiving the item doesn't have the proper FFL, and file
the paperwork, they are SOL and might as well just junk it or keep it
hidden away. Transfers between FFL holders require paperwork to the ATF,
but don't incur the tax.

So if you make your own, put it in a locked box and don't show it to
anyone, or tell anyone about it (especially psychotic female roomates,
girlfriends or wives, since I know of two fellows who owned such weapons
and were ratted on by such after breakups).

The NFA of 34 and the FOPA of 86 do not cover lasers, masers, or emp
devices, though these may be classified as Destructive Devices if
powerful enough.
