Less than a year after Maiman's paper, researchers at Bell Labs in New Jersey, USA, described the first gas laser. Again ... they analysed the Fourier spectrum of the maser output, which was ...

The far-infrared is the part of the electromagnetic spectrum loosely defined as extending from about 10 micrometers ... Commercial far-infrared lasers emit at wavelengths from about 28 ?m to 2 mm. A ...

spectrum. Carbon dioxide lasers almost always emit light within the 9.4 μm to 10.6 μm band, which corresponds to roughly 28.3 terahertz (THz) to 31.9 THz. As mentioned above, the ability to vary gas ...

There are many different types of lasers—almost as many as there are applications for the same—but what ties them all ...

Alongside carbon dioxide, methane is a key driver of global warming. To detect and monitor the climate pollutants in the atmosphere precisely, scientists have developed an advanced laser technology. A ...

Scientists at the Max Planck institute for the science of light developed an advanced laser system for precise detection of ...
