Happy Canada Day to all our Canadian members on this list! And as a special treat, here's a famous Canuck telling us how he feels about being a Canadian: ...
Or, as another way of poking fun at my motherland and all those dastardly loyalists who didn't know a good thing when they saw one, shouldn't it be "Happy...
I've put up a back-of-the-envelope calculator for the damage of heat rays to materials on my web site http://panoptesv.com/SciFi/DamageAverage.html I hope some...
WOW! Neat stuff! The calculator is valid for fempto/nanosecond pulsed lasers and stuff? Thank you Very much! Filipe "Adtollite portas principes vestras Et...
... It might be worth talking about peak intensities in air. Air becomes less transparent at very high intensities because of multi-photon absorption (typical...
... I'm glad you like it. It can handle the thermal effects for a pulsed beam if you enter the time average power level, but it does not deal with the...
... I discuss this briefly on another page http://panoptesv.com/SciFi/Ionization.html but if you know of any good reviews or references on the subject, I'd be...
... Nope, I don't know of any. Lemme think about this in a theoretical way. Assume that the way two-photon absorption works is that the two photon waves get...
... Yeah. Gas doesn't leave instantly. ... Hence "somewhat difficult". It's by no means impossible. You're also ignoring ionization. Also, if the vapor becomes...
... For a laser that fires a single pulse, yes. For a laser that fires multiple pulses, no (at best, it will drill through the shield just like any other...
... Even if the gas hangs around for a while, if you are evaporating one gram of material per second, one gram of gas per second will be leaving. If it...
Hm. I've found something that looks like it may be a useful reference: http://www.mrl.columbia.edu/ntm/pgIndex.html It's about laser machining, not death rays,...
... Here are the reasons I suspect it may be better. First the shock from blowing through each layer is allowed to expand instead of being caught at its...
... If the shock is strong enough, yes. You would need on the order of a Megajoule or so to get this effect. Modern ICF lasers are approaching this pulse...
We need 14 more pre-orders by July 14th to put this on to press with another product. Squadron Strike is a hex based game with a ship design engine that works...
... Compressive shock is not particularly good at destroying armor, unless the armor is thin enough to be broken apart. On a monolithic plate, the primary...
... Do firing arcs differ depending on the heft of a weapon? A spinal mounted X-ray wiggler or MFT direct powered UV death blaster is simply going to require...
... blaster is simply going to require turning the entire ship to change targets while a railgun point defense turret could cover a hemisphere without much...
... Hm. To what degree is this dependent on the thickness of the armor? When spalling occurs, is it always a certain amount of metal breaking off, or is it a...
... There is certainly some effect of armor thickness, since shocks lose energy as they pass through the medium. Thus thicker armor will have a weaker shock...
... I just thought of another wacky idea. How about using a rapid cycle rate laser that plays across the hull at the speed of sound? Thus, the shockwave of...
