A new absolute distance measurement system is demonstrated in this paper, which is based on a dual-wavelength passive mode-locked fiber laser. By controlling the intracavity loss and spectral ...

Astronomers from the University of Turku in Finland and elsewhere have performed a broadband spectral and timing study of an ...

A femtosecond (fs) laser direct inscribing dual-wavelength fiber laser was proposed and experimentally demonstrated. A unique double-peak reflection spectrum can be produced when a fiber Bragg grating ...

Some planets take the expression "you're your own worst enemy" to the extreme — triggering stellar flares from their own ...

Using the Very Large Array (VLA), astronomers have performed radio observations of a galaxy cluster Abell 2744, nicknamed ...

The first ever space telescope, the Orbiting Astronomical Observatory 2 (OAO-2), was launched into the low Earth orbit in ...

The CO2 electrochemical reduction reaction (CO2RR) has intrigued scientists for decades as a way to make fuel and chemicals ...

NASA's Chandra X-ray Observatory provides a new look at the Andromeda galaxy in this multi-wavelength image that includes ...
