Previous methods for generating chirped optical frequency combs relied on complicated and costly arbitrary waveform generators.
A new approach for electro-optic frequency comb generation, which overcomes the high cost, size, and power consumption of arbitrary waveform generators while offering higher frequency agility.
This invention can be utilized to perform a wide variety of measurements including molecular and atomic spectroscopy as well as physical metrology for applications such as pressure, temperature, vibration, sound, ultrasound, and numerous other areas.
This approach is far more inexpensive than previously demonstrated approaches that rely upon arbitrary waveform generators. In addition, it does not require the transfer of large time records, which limits the frequency agility and flexibility of the method. Further, coherent operation and coherent averaging have been demonstrated which allow for facile averaging.
