Turmeric and coffee: the surprising ingredients for generating short-pulsed laser

Fiber lasers have emerged as a highly versatile and reliable technology, widely used across scientific, medical, and industrial domains. Compared to bulk lasers, they offer superior performance thanks to their compact and easy-to-use design, which eliminates the need for complicated alignment procedures. The pulsed operation of the fiber lasers is particularly beneficial as it allows for a significant boost in instantaneous power, enabling the driving of nonlinear optical processes and facilitating high-resolution, time-resolved applications.
