The CEP accessory for Micra generates carrier-envelope phase stabilized ultrafast laser pulses. It combines our  highly flexible and stable broadband ultrafast Micra laser (Micra-5 or Micra-10) with a carrier-envelope phase detection module and fast-feedback electronics.

By active feedback control of the laser, the CEP stabilizer locks the phase velocity of the oscillating light field to the group velocity of the phase envelope. Thus, for ultrashort pulses consisting of only a few optical cycles, the peak of the oscillating electrical field can be maximized under the phase envelope.

At the heart of the CEP module is a non-linear interferometer. This unit uses a photonic crystal fiber to generate an octave-spanning optical spectrum. The red end of this spectrum is frequency-doubled and combined with the green end of this same broad spectrum. The resultant beat frequency is sensed by a fast photodetector that provides the CEP feedback signal. After suitable processing, this signal is then used to control a fast cavity mirror actuator inside the Micra laser, thereby controlling the carrier phase.

The Micra with CEP stabilizer is a powerful and flexible broadband laser source for the emerging fields of attosecond research, high harmonic generation, optical clocks and coherent control. The ultra-low-noise performance of the Verdi pump laser built into the Micra is a key element in the unique performance capabilities of the Micra CEP system. You get cutting-edge performance that's readily available for practical use. From another unique product that brings you Better Ultrafast, Every Day.
