Femtosecond Ti:Sapphire Laser System
_ CEP Stabilized
 |
Based on our Octave-Spanning (OS) Edition the VENTEON | PULSE : ONE CP is a complete carrier envelope phase (CEP) stabilized system, which includes in addition to our octave-spanning oscillator an f-to-2f interferometer for generating the required fCEO beat signal with excellent signal-to-noise ratio and all necessary stabilization and control electronics. |
|
Due to the octave-spanning output spectrum the CEP-lock can be done directly without any additional spectral broadening or the need for difference frequency generation in a nonlinear crystal. An accurate filtering of the spectral wings, needed for the f-to-2f self-referencing technique, allows for more than 90 % of the original output power remaining with unchanged beam quality for subsequent experiments. |
|
The VENTEON | PULSE : ONE CP can be ordered with an option to stabilize the carrier-envelope-offset frequency to zero generating a pulse train with constant CEP. It is the first commercial system of this kind with unique specifications. This system allows for field sensitive experiments at full oscillator power and repetition rate without the need for pulse picking. |
|
Our CP Edition includes an extended water-cooled breadboard with reserved space for a pump laser installation within the laser enclosure and a direct location of the interferometer next to the oscillator. |

| Laser output spectrum without filter for CEP stabilization (blue) and usable spectrum with CEP-lock (red). | fCEO beat signal from an f-to-2f interferometer featuring a signal-to-noise ratio greater than 35 dB in a 100 kHz resolution bandwidth suitable for a robust CEP-lock. | Clean stabilized fCEO-beat at 20 MHz shown in a 100 Hz span with 1 Hz resolution bandwidth. |
First Oscillator Pulse Train with Constant CEP
|
Optional the VENTEON | PULSE : ONE CP can be ordered with carrier-envelope-offset frequency locked to zero generating a pulse train with constant CEP. This system allows for field sensitive experiments at full oscillator power and repetition rate without the need for sophisticated pulse picking, not possible for such few-cycle pulses without destroying the pulse. |
|
The identical pulses feature a CE timing jitter of less than 100 as. The stability is high enough to allow for a perfect interference contrast of more than 10^11 pulses. |
 |
| Laser output spectrum without filter for CEP stabilization (blue) and usable spectrum with CEP-lock (red). Out-of-loop measured interference of 10^11 oscillator pulses proving an excellent CEP lock*. The CEP can be tuned by inserting glass wedges in the extra-cavity beam as shown in the middle part of the picture. |
