A laser-ion engine is a device that uses a combination of a laser and an ion engine to create a cascade of discharges that accelerate particles and lead to thrust generation.

The scheme of the laser-ion engine includes the following main components:
1. Laser – used to excite and accelerate electrons in the ionization of the working gas.
2. Power supply – provides power to the laser and other engine components.
3. Optical system – directs the laser beam to the ionizer, where the ionization process takes place.
4. Ionizer – responsible for the ionization of the working gas by irradiating it with a laser and creating plasma.
5. Ion accelerator – accelerates and directs charged particles towards the nozzle, creating thrust.
6. Nozzle – releases accelerated ions at high speed, which generates thrust and ensures the movement of the spacecraft.
which allows the use of a laser to generate and accelerate ions, which leads to the creation of high-precision and powerful thrust to move spacecraft.

laser-ion engine works by ionizing and accelerating gas ions using a laser. The process begins with the ionization of gas inside the engine using laser radiation. When gas atoms become ionized, they acquire a positive or negative charge and become ions. The electric field inside the engine then accelerates the ions and drives them out of the engine at high speed, creating thrust.

This type of engine is commonly used in spacecraft to change their speed and direction of flight. The laser-ion engine has many advantages such as high efficiency, long service life and the absence of stationary parts, which makes it ideal for long-term space missions. However, this type of engine usually has low thrust, so it is mainly used for maneuvering in outer space.

The device consists of a source of pulsed laser radiation, an optical node with a radiation concentrator, the first reflector of which is made in the form of a mirror cone-shaped figure of rotation, the forming surface of which is a part

of a short-focus parabola forming an optical system for receiving and matching the aperture of the laser beam with the dimensions of the optical node and the formation of a flat radiation front, as well as a gas-dynamic node located coaxially with the hub.

. A pulsed periodic laser has been selected as the source of laser radiation. From a laser pulse-periodic radiation source, the beam enters the forming optical system. In the proposed design, laser radiation is supplied to the engine unconventionally, i.e. not from the nozzle side, but from the opposite side. From the forming optical system, the beam is directed to a radiation concentrator consisting of two reflecting mirrors. When hitting the first mirror cone-shaped reflector O1, due to the fact that the surface forming it is made in the form of a segment of a short-focus parabola, and the incident beam is flat, the beam is reflected and focused. Next, the beam hits the O2 reflector. One of the foci of the O2 reflector is combined

with the focus of the O1 reflector, and the second focus of the O2 reflector is combined with the area of formation of the laser breakdown of the working medium of the engine. Next, the reflected beam is focused at a point behind the reflector O1, forming an optical breakdown.

When laser radiation interacts with the working medium of the engine, its optical breakdown or evaporation occurs, and plasma is formed that absorbs laser radiation. As a result, a system of shock waves and satellite flows behind them is formed, leading to the formation of a gas dynamic flow directed to the outlet part of the nozzle and to the creation of jet thrust. The working medium of the engine is supplied to the optical breakdown area. Gaseous, liquid or solid fuels are used as the working medium. The disadvantage of this technical solution is the displacement of the center of gravity of the engine to the forward point due to the peculiarities of finding the source of laser radiation, and, as a
