We've boosted the laser's power output by five times to more than 50 mW, decreased its lasing threshold ... the emitted wavelength to the mid-infrared range and creating a room-temperature mid ...

Lasers are known for the monochromatic nature of their light, so much so that you might never have thought there could be such a thing as a white laser. But in the weird world of physics, a lot of ...

The color of a laser pointer's dot or beam corresponds directly to the wavelength it emits. While all lasers are capable of emitting visible as well as ultraviolet and infrared light ... or milliwatts ...

The researchers, led by Ursula Keller, professor at the Institute for Quantum Electronics, have set a new record for short and strong laser pulses: at 550 watts of average power they surpass the ...

The related finding was published in Optics Express. ~ 2-μm near-infrared lasers are crucial in areas like medical surgery, lidar, and scientific research. These lasers can be created by using a ...

When molecules are irradiated with infrared light, they begin to vibrate ... the team drew on preliminary work from the early days of laser spectroscopy, some of which was decades old, and used ...

Infrared Light Emitting Diodes (IR LEDs) are a type of LED that emit light in the infrared spectrum, which is invisible to the human eye. These LEDs are typically used in applications where infrared ...

Earlier this year the U.S. Army shot down a number of hostile drones in the Middle East using a weapon long dismissed as more science fiction than reality—the laser. After decades of costly ...

Croatian electricity and gas regulator Hrvatski Operator Tržišta Energije has launched a tender for 88 MW of renewables capacity. The authority aims to allocate 50 MW of solar capacity ...

You know that feeling when your phone gets the much-needed updates with all the features you've been wanting? That's exactly ...
