According to the team, the laser has demonstrated an order of magnitude more output power than its predecessors, while the tuning range has been enhanced by more than 100%.
“We have always been a leader in high-power and high-efficiency lasers,” said Professor Manijeh Razeghi. “Combining an electrically tunable wavelength with high power output was the next logical extension.”
Mid-infrared spectroscopy allows chemicals to be identified through their unique absorption spectra. This enables the detection of hazardous chemicals or possible explosives. Because Prof Razeghi’s system is also directional, the high power can enhance the ability to detect chemicals. The technology could also find application in free space optical communications and aircraft protection, says the team.
