Laser systems can (re)create cosmic shockwaves.

The simplest way to make the laser-explosives is the bottle of pressurized gas that the laser system explodes. There the laser system cuts the hole. The laser detonates the gas. 

That thing can make the gas bottle detonate precisely at a highly accurate point. 

Lasers are impressive tools. They can accelerate particles at a very high speed. In some weapon solutions, laser beams shoot bullets above the enemy positions. 

The laser system expands the object very fast. That causes an explosion and shockwave. So the laser weapon can blow objects over the target. The laser system can also make it possible to create high-power shockwaves if they are aimed into the air. That makes it possible to create high-power acoustic waves. 

Plasma-laser systems can also form ions and increase their speed. The plasma-lasers-ion accelerators are the ion accelerators or ion cannons where the lasers give extra energy to those particles. 

Laser systems can also use those shockwaves in the new engine technology. Researchers research the possibility of replacing the combustion in rocket and jet engines. Lasers can heat the propellant and then make shockwaves that push aircraft or rockets forward. In traditional ion engines, lasers can vaporize things like metals. The system drives that vapor in the magnetic accelerator. 

In new systems lasers or ion-laser hybrid systems shoot high-energy laser- or laser-particle beams into the propellant. That causes propellant expansion. 

When we think about things like plasma engines. The laser can ionize gas that the system can drive past the craft. That thing can drive plasma over the craft and it can make the ultimate stealth system. The plasma engine can also pull ionized gas over the wing.

That can make the aircraft hover in the air. 

The system must only be careful. That there is low pressure above the wing. 

The Chinese claim to have developed the laser propulsion system for submarines.  Their laser can simply boil water in the rocket engine chamber. They plan to install that engine into the submarine. 

The system can also inject things like metal or carbon particles into the chamber and lasers will pump energy into them. That makes the system more effective when laser beams hit those particles and water which causes very fast expansion. That kind of system can push craft in water or air. Another thing that the laser system can make is the system that pushes air or water away from the craft's movement direction. 

If the laser system can create a low-pressure area in the aircraft's direction that low pressure will pull it forward. That thing makes it possible to create the systems that allow the ultimate high-speed flight in the atmosphere. Similar systems can make it possible to create submarines with ultimate speed. If a laser beam can push air away from the rocket's or a plane's route it can create a low-pressure channel that decreases friction. 

The cosmic void is one version of the WARP bubble. So if researchers can create a shockwave that pushes the quantum fields away from the craft's route that should act similar way as the laser beams act in the air. The energy that comes from the back of the object pushes the object forward. If that kind of effect is strong enough, that thing can make the space where the speed of light is higher than its environment. That system can create some kind of WARP bubbles at least in the miniature scale.
