"So far, our work has focused on demonstrating the concept by examining the instantaneous laser linewidth," says Professor Mildren. "Our next steps will involve adapting advanced cavity design and ...

LASCAD version 3.5.4 incorporates Dynamic Multimode Analysis (DMA) designed to improve the computer-aided design of Q-switched solid state lasers. The DMA code provides: computation of shape and ...

To refine the laser’s performance and achieve precise wavelength control, the researchers engineered an innovative intra-cavity design featuring microring-based Vernier filters, a type of ...

They are generated within the active media of a laser by shining light on the cavity and they can be reset by using an equivalent process. These cavity solitons are bistable, which means that they can ...

Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special technique to film laser light in real time, researchers observed how ...
