  Applications of Femtosecond Laser Frequency Combs

  Cutting-edge applications of femtosecond laser frequency combs, such as astronomical spectrometer calibration and high-speed data transmission, require lasers with repetition frequencies of 10 GHz and above, far exceeding the typical 100 MHz of femtosecond lasers. Fortunately, recent technological breakthroughs now allow continuous wave (CW) lasers to be modulated at frequencies above 10 GHz, providing robust, flexible, and stable frequency combs at ultra-high repetition rates.

  Application Scenario 1:

  Precision Metrology: In practical measurements, measuring the wavelength of a laser with a spectrometer or wavelength meter cannot achieve such high accuracy, thus requiring an optical frequency comb to measure the frequency of light.

  Application Scenario 2:

  Frequency Reference: Similar to precision metrology, in applications where the optical comb is used as a frequency reference, the comb lines of the optical comb are used to beat against the frequency of the CW laser under test.

  Application Scenario 3:

  Optical Fiber Time-Frequency Transfer: With the development of optical fiber communication and the internet, optical fibers have closely connected the world. The establishment of optical fiber networks also facilitates clock comparison and synchronization worldwide.

  Application Scenario 4:

  Precision Ranging: Accurate distance measurement is of great significance in satellite formation flying, planetary space positioning, large structure shape measurement, micro-displacement measurement, and industrial manufacturing measurement.

  Application Scenario 5:

  Precision Spectral Measurement: Due to the high bandwidth, short-term and long-term stability of femtosecond optical frequency combs, they are gradually being explored and applied in the field of high-precision spectral measurement.
