Small and Energy-efficient Semiconductor Laser
Austrian scientists of the University of Linz has newly developed a small and energy-efficient semiconductor laser, which can be widely used in fields such as environmental analysis, climate research, medical and automotive exhaust gas monitoring.
According to Austrian Press Agency (APA) on Thursday, using lead-salt semiconductor, scientists of the Institute of Semiconductor and Solid State Physics, the University of Linz, have produced a laser with its wavelength up to 4.3 microns.
However, this kind of equipment should be used in cooling environment with the operating temperature of up to 2 degrees Celsius.
The researchers said that the new infrared semiconductor laser can be used to develop a “more compact, more durable, cheaper, and with higher energy efficiency”laser system.
Although it still needs a cooling condition to be used currently, it has the possibility to work at room temperature in the near future, said the scientists. (PNA/Xinhua)
