venteon CEP5

The Laser Quantum venteon CEP5 laser is a complete carrier-envelope-phase (CEP) stabilised laser system that utilises the exceptional spectral characteristics of the venteon ultra oscillator for a direct realisation of sub-two cycle CEP stable laser pulses with less than 50 as timing jitter. The CEP5 locking approach is the most natural way of locking the CEP by only filtering the spectral wings and is thus efficient and low-noise. Most importantly, it does not affect the properties of the ultrashort output beam by avoiding refractive elements as an AOFS in the beam path. In addition to the CEP-ready octave-spanning oscillator, this system includes an f-to-2f interferometer for fCEO beat generation next to a low-noise pump laser with CEPLoQ??? technology, locking electronics by Menlo Systems (Syncro) and measurement equipment.
