. The ZKZM-500 can reportedly fire a thousand two-second shots, the equivalent of 33 hours of laser power


2000 seconds is 33 minutes

True ,pulsing could extend battery life , focusing would be better but the whole package makes it very iffy in my mind. You have to make too many assumptions to get this thing to work. Physics, making good ideas hard to do. :D

Presuming the laser gun does work, mirrors. Retro-reflector corner cubes even. Or for improvised protection, aluminum foil, shiny side out.

Realistically, the battery alone would have to weigh several hundred pounds to provide the energy needed to fire a hot laser beam a kilometer. The beam itself would have a hard time once it left the gun. As the beam passes through the air the water molecules in the air—the 'heat' of the beam would disseminate very quickly.. A far cry from the "instant carbonization" threat that is being touted by the chinese,at least at the ranges they are claiming. Cooling of the gun is another factor, no process is 100 percent efficient. and I see no heat sinks or cooling anywhere.

BUT BUT ...PHYSICS , Thermodynamics ,OPTICS

Future lasers might have an efficiency of 20-50%. At the low end, a weapon with a 1kJ beam will have to dissipate 4kJ of waste heat with each shot.
Our best lithium-ion batteries have a specific energy of about 1.8 MJ/kg. A single 7.62 NATO round has about 3.3kJ when fired. so your talking two kilo of battery power for each shot to equivalent to a nato round For a laser to have the same effect at this range The soldiers will have to carry around portable power packs, or be plugged in. A super battery material like discussed in the other thread for a laser gun would be more usefully deployed as an explosive warhead'. A direct hit on the power pack of a laser gun will be like a equivalent weight of TNT exploding.
optics would have to be flawless and easily replaceable in the field by a soldier. Any dust or dirt on the lens would be catastrophic if /when fired Have you ever been in the field?
Perhaps the biggest unaddressed problem of laser weapons is their ability to permanently blind anyone who happens to see the beam. In practice, this means anyone within a 5 km radius - roughly the limit of the horizon - is at risk. If a laser beam is powerful enough to incapacitate someone, a reflection off any shiny object - a well-polished car, a window, a doorknob, shiny rivet- will blind anyone unfortunate enough to be in the (reflected) line of fire. Near-IR beams will ignite dust and pollen in the path of the beam; visible light will, obviously, be visible; near-UV will produce a fluorescent glow along the beam. pointing out the position of the shooter
Maybe given time and great development it would be useful in special case scenarios like seal team snipers
Mounted on a platform, very doable, but as a common foot soldier weapon ,no. A M4 is cheaper less prone to failure and field serviceable with the same lethality. China is full of sh!t

I've been toying with the idea of electrically powered slug throwers in place of gunpowder. Energy density in the battery isn't anywhere close to a problem. Power density, particularly for higher energy rounds, does look like a problem. My focus has been on electrically powered air guns, and a compact air pump for the required power and pressure is non-trivial, though a solenoid based system =might= be workable.

I love the internet, ask and you shall receive. while you did have some innovative solution, physics still wins
(at least with our current technology)
range is one of the major limiting factors

I think the bottom line is best described by an old welsh proverb.

China, like Russia, and others loves the idea of information campaigns. They are comparably very cheap when compared to actual functional capabilities and capacities. The part those who like information campaigns don't tend to understand often are the unintended consequences. Sadam comes to mind. As do others, such as Hitler.

I would apply to old adages here; "If it sounds to good to be true...", and, "Show me."

Burning a hole in a human at 800m is a substantial accomplishment at the shoulder fired level. There are so many competing issues, the most basic of which is atmospherics, as well as the claimed magazine depth for the required power levels delivered on target at range. I remain highly sceptical, as I do of many claimed capabilities out there. I too think the PLA is "Full of shit" in many ways.
