Light Clock
An optical clock is a device that uses atomic or ionic transitions within the optical frequency range to measure time, with precision far exceeding that of current microwave frequency-based atomic clocks. It is the gold standard of time and the ultimate pursuit of technology. The working principle of the optical clock is to lock a femtosecond laser frequency comb to an optical frequency standard, thereby achieving ultra-high precision time measurement. The development of this technology is expected to make optical clocks the future standard for redefining the "second." With technological advancements, the precision of optical clocks continues to improve, and they are expected to play important roles in fundamental physics research, global positioning systems, precision measurement, and other fields.
The application of optical frequency combs in optical clocks is mainly reflected in the following aspects: 1) Frequency measurement: Optical frequency combs can precisely measure the optical frequencies used in optical clocks, providing frequency standards for the clocks. 2) Frequency conversion: Optical frequency combs can convert optical frequencies to microwave frequencies, enabling measurement and synchronization across different frequency ranges. 3) Frequency stabilization: By comparing and locking the frequency components of the optical frequency comb to the clock's frequency, precise control and calibration of the optical clock frequency can be achieved, thereby improving the clock's stability and accuracy.
Our company's optical frequency comb, equipped with a unique resonant cavity design and high-performance locking technology, provides a precise and stable frequency source for optical clocks. The one-button start operation makes complex frequency measurements simple and fast. Repetition rates of 100MHz, 200MHz, and 250MHz are available, with frequency stability under optical frequency reference better than 5E-16; our company's highly stable, fully locked optical frequency comb, as a key technology connecting optical and radio frequencies, will continue to play an important role in the development of optical clocks.
