07 Jul 2008 Precise pulsewidth measurement with the most flexible device out of our family of autocorrelators. APE PulseCheck has a specially designed, spring loaded linear delay drive which allows you to choose the scan range according to the pulse duration. This offers high accuracy and large duty cycle. Because of the friction-free movement there are scan ranges down to 150 fs.
The delay is measured online with high resolution to stabilize scan amplitude and to ensure a linear, calibrated time scale. This also provides the capability to measure interferometric autocorrelation functions. |
