A high-brightness ultrabroadband supercontinuum white laser has attracted more and more attention in physics, chemistry, biology, materials science, and other disciplines of science and technology.

There are obvious differences between cancerous cells and normal cells in morphology, chemical properties and mechanical properties. The detection of cytochemical and mechanical properties of tumor ...

For years, scientists have fabricated small, high-quality lasers that generate red and blue light. However, the method they typically employ — injecting electric current into semiconductors — hasn’t ...

For decades, laser engineers have wrestled with an embarrassing blind spot: the green-through-yellow slice of the visible spectrum, roughly 532 to 633 nanometers, where compact semiconductor lasers ...
