Powerful Laser May Lead to Cutting-Edge Hologram Technology

Chinese scientists have developed a powerful laser that could be the key to cutting-edge hologram technology, as reported by Interesting Engineering. The laser pen can write in the air to produce patterns.

To burn or write in the air, the pen emits high-intensity laser pulses to create ionised gas or plasma. In turn, this emits energy in the form of light. The laser has been created by researchers at the Hongtuo Joint Laboratory in Wuhan, China. The peak power of the laser pen can reach a million megawatts due to the incredibly brief pulse duration, which is comparable to the whole utility-scale electricity producing capacity of the US, but only for a few femtoseconds.
