Making a Mini Laser Frequency Comb in Minutes

The video tutorial introduces a new technique for creating microresonators, which are small optical cavities that confine light. These are used at NIST for optical frequency metrology and creating optical frequency combs, which are precise tools for measuring light frequencies. Traditional comb technology is compared to new methods using millimeter-scale glass and low-power lasers, which are more compact and efficient. The video demonstrates the fabrication process using a carbon dioxide laser to shape glass, resulting in high-quality microcavities. The new techniques allow for a wide range of frequency comb spacings and have potential applications beyond the lab.
