How Does Infrared Laser Technology Transmits Power?

The demand for portable wireless battery chargers is increasing as the electronic gadgets in daily life need an uninterrupted power supply 

Researchers at Sejong University in South Korea have developed a new infrared wireless charting system that transmits the power over a distance of up to 30 meters.

Researchers found a method called distributed laser charging for providing safe high-power illumination with less light loss.

The new Infrared wireless charging system is made up of two components, a transmitter, and a receiver.

The transmitter is an optical power source used for producing a beam of infrared light with a wavelength of 1550 nm.

The receiver is made up of a retroreflector (photovoltaic cell) that transforms the optical signals into electric energy.

The infrared laser charging system could provide an optical power of 400 nm and the photovoltaic converted this to electrical power of 85 mW
