I'd love to see a copy as well.

I don’t know if list etiquette here allows attachments.
Anyone who’d like a copy, let me know.

Jordin, do you have a paper of presentation you can share with us? I
wanders for a moment, if designed for it you should only get a mixture
I particularly like how the engine doesn't flame out if the beam
shift and thrust decrease, not complete loss. A brief beam interruption
would only cut into margins, not cause loss of vehicle. Sweet!

It puts more energy into the propellant, raising the Isp.
Straight LOX-NH3 has an Isp of only 354 s under the same conditions.
Not enough for SSTO.
Being able to burn straight LOX-NH3 is useful to provide high initial
thrust, though, or to provide thrust with reasonable Isp for part of
the trajectory when laser power isn’t available.

X-15 engines burned LOX-NH3(L). Why crack the NH3 at all?

How about a density of 0.868 kg/l and 410-420 sec. vacuum Isp
(@100:1 expansion)?
You can do that with LOX-ammonia and some laser power to heat the
ammonia and turn it into H2 and N2.
Takes about 1/4 the laser power of a pure laser rocket. I talked
about it at the last Space Access meeting:
the Liquid Oxygen - Laser Cracked Ammonia Thruster (LOLCAT :-))
