Researchers Develop New Energy-Efficient Semiconductor Laser

Researchers at the University of Linz in Austria have developed a new tiny and energy saving semiconductor laser for use in various fields. The laser is ideal for use in fields including automotive exhaust gas monitoring, medical, climate research, and environmental analysis.

Researchers at the university’s Institute of Semiconductor and Solid State Physics used the lead-salt semiconductor to manufacture a laser that has a wavelength of up to 4.3 µ. The laser can be utilized in a cooling environment with a maximum operating temperature of 2°C.

According to the scientists, the infrared semiconductor laser can be utilized to produce a cost-effective, durable, compact and energy-efficient laser system. The researchers added that currently the laser requires a cooling condition for its use, and still the laser can operate at room temperature in the future.
