What Is an Electrolaser?

Laser power transmission is a form of laser-based power transmission. Due to the strong directivity and energy concentration of the laser, the laser can carry a large amount of energy. Therefore, it is possible to achieve long-distance power transmission with a small transmission power.

Similar to microwave power transmission, laser power transmission uses lasers to transmit electrical energy. The laser is a high-intensity, high-intensity beam with a fundamental frequency between 04 and 106 GHz. The directivity of the laser is strong, and the conversion efficiency can reach 45%. The laser can carry a large amount of energy, and the conversion of laser energy to electrical energy can be completed by a photovoltaic cell.

Compared with the traditional power transmission, the obvious advantage of laser power transmission is that there is no requirement for electrical insulation, and the advantage of electron transmission is that there is no requirement for magnetic field insulation. ^[1]

The main disadvantage of laser power transmission is that there is electromagnetic radiation from the mutual conversion between electric power and light. In the future, high-power laser beams will be considered for transmission in evacuation catheters and distributed with optical fibers. The problem is to avoid the catheters being burned out of the holes by the laser.

Microwave is an electromagnetic wave with a wavelength between radio waves and infrared radiation. It is widely used in microwave ovens, weather radars, navigation and mobile communications. Unlike radio medium and short waves, microwaves can pass through the ionosphere without reflection.

The principle of microwave transmission is: firstly, the electric energy (DC or AC) is converted into microwaves by a microwave converter, and then the microwaves are transmitted to the space through the microwave transmitting antenna of the transmitting station. Microwaves are transmitted from space to ground receiving stations. The received microwave is converted into power frequency AC power by a converter. For users. Therefore, the principle is similar to the principle of radio transmission, except that the energy level and direction of the transmission are different ^[2] .
