Explanation:

The term was initially an acronym for Light Amplification by Stimulated Emission of Radiation.
• A polariton is part light and part matter. Polariton lasers harness these particles to emit light.
• They are predicted to be more energy efficient than traditional lasers. The new prototype requires 250 times less electricity to operate than its conventional counterpart made of the same material.
• Polariton lasers don’t stimulate radiation emission. They stimulate scattering of polaritons.
• It is fuelled by electrical current as opposed to light, and also works at room temperature.
• For the past 50 years, we have relied on lasers to make coherent light but this is an entirely new technology based on a totally new principle as admitted by researchers.
• It represents a milestone like none the field has seen since the invention of the most common type of laser – the semiconductor diode – in the early 1960s. Polariton beam, using 250 times less power, could revolutionize electronics.
