UCF Scientist Creates Most Efficient Quantum Cascade Laser Ever

A team of UCF researchers has produced the most efficient quantum cascade laser ever designed – and done it in a way that makes the lasers easier to manufacture.

Quantum cascade lasers, or QCLs, are tiny – smaller than a grain of rice – but they pack a punch. Compared to traditional lasers, QCLs offer higher power output and can be tuned to a wide range of infrared wavelengths. They can also be used at room temperature without the need for bulky cooling systems.
