Title: NIST Develops Direct Digital Chirp Synthesizer for Generating Chirped Optical Frequency Combs
Summary:
The National Institute of Standards and Technology (NIST) has developed a new direct digital chirp synthesizer that can generate chirped optical frequency combs. This synthesizer consists of two main components: a direct digital synthesizer and an electro-optic modulator.
The direct digital synthesizer receives a repetition frequency signal from a delay generator and a clock frequency from a frequency converter. It then produces a radiofrequency chirp waveform based on these signals and communicates it to the electro-optic modulator.
The electro-optic modulator, in turn, receives the radiofrequency chirp waveform from the direct digital synthesizer and laser light. It uses the radiofrequency chirp waveform to modulate the laser light, producing a chirped optical frequency comb.
This new synthesizer is designed to generate chirped optical frequency combs with high precision and stability, making it an essential tool for researchers and scientists working in quantum optics and spectroscopy applications. The ability to produce these combs efficiently and accurately will likely accelerate advancements in these fields.
