NIST physicists have developed a new type of ultrafast laser that pulses 100 times faster than conventional lasers, using common electronics and a simple aluminum cavity. The new electro-optic laser could revolutionize fields like chemical and biological imaging by enabling real-time hyperspectral imaging.
The key innovation is a filtering method that reduces heat-induced interference, allowing electronic signals to stabilize and filter light consistently. Unlike traditional optical frequency combs made with complex mode-locked lasers, NIST’s new laser uses microwave electronic vibrations on a continuous-wave laser to create ultrafast pulses.
The technology offers unprecedented speed while maintaining accuracy and stability comparable to conventional lasers. It’s built with commercial components, making it highly reliable. Potential applications include faster data acquisition for optical clock networks, communications, and sensor systems.
The research is supported by multiple government agencies, indicating strong interest in advancing this technology for various applications.
