Quantum Dot Breakthrough Makes Infrared Lasers Affordable and Scalable

Researchers have developed a new laser technology using large colloidal quantum dots of lead sulfide to emit coherent light in the extended short-wave infrared range. This innovation promises cheaper, scalable laser solutions compatible with silicon CMOS platforms, covering a broader wavelength range without altering chemical compositions, and eliminating the need for costly femtosecond laser amplifiers.
