Physicists have created a compact laser that emits extremely bright, short pulses of light in a useful but difficult-to-achieve wavelength range, packing the performance of larger photonic devices ...

The AMTM measures and records the brightness of light at specific wavelengths, which can be used to create air and wave temperature maps. These maps can reveal the energy of these waves and how they ...

we present a single-longitudinal mode (SLM) Ytterbium-doped fiber laser (YDFL) featuring a six-subring cavity (SSRC) structure. The YDFL achieves SLM output through use of the SSRC architecture. We ...
