Industry Innovations in Fiber-Based Frequency Combs: Ultrabroadband Comb with Sub-3-kHz Free-Running Linewidths
Tue, Aug 27, 2024 1:00 PM - 2:00 PM EDT
Femtosecond frequency combs represent unparalleled measurement tools with diverse applications in spectroscopy, metrology, and quantum physics. This discussion delves into the critical aspects of maximizing the passive stability of these instruments to unlock their full potential in fundamental science and high-tech industries. By studying the noise properties of fiber-based frequency combs across varying intracavity dispersion, pump power, and repetition rate parameters, researchers have notably identified distinct minima where the free-running linewidth of the carrier-envelope offset (CEO) frequency (fCEO) drops below 1 kHz. A comprehensive analysis of individual comb lines across a broad spectral range unveils the specific contributions to phase noise and their interplay. Leveraging these insights, this presentation showcases the development of frequency combs with sharp teeth at designated positions throughout the spectrum from fCEO to 300 THz. These compact systems offer ultrabroadband stability, presenting a new standard for front-end measurement, such as integrated quantum clock experiments based on Strontium atoms.

Reflective Optics for Multispectral EO Systems
Wed, Aug 28, 2024 9:00 AM - 10:00 AM EDT
Large reflective optics are essential for high-performance multispectral electro-optics imaging systems in defense, surveillance, and aerospace. These systems capture multiple wavelengths to improve target identification and combine data from various bands to offer a comprehensive environmental view, enhancing situational awareness. They excel in adverse conditions by penetrating haze, smoke, and challenging weather better than visible light, and they provide high-resolution imaging for detailed analysis and accurate decision-making. Utilizing advanced data fusion, these systems enhance target recognition and tracking, adapt to various mission requirements from surveillance to disaster response, and reduce operational costs by minimizing the number of necessary maneuvers.
