ROC Autocorrelators
Pulse duration measurement made easy
Optical autocorrelators are used to measure pulse duration of ultra-short laser pulses. The principle is to create two copies of the laser beam of interest with a beam splitter. The copies are superimposed in a nonlinear medium (SHG crystal), where they interact generating a third beam. As the overlap of the two copies depends on the pulse duration, analysing the third beam allows to calculate the pulse duration.
Single pulses and repetitive pulses
get immediate results even on single-pulses
Easy to Align
saves up to 90% time compared to conventional autocorrelators
Pulse measurement starting at 4 fs
accurate results on femtosecond and picosecond pulses
ROC Single-Shot Autocorrelator
A single-shot autocorrelator measures both the pulse width of single pulses as well as repetitive pulses. Very compact and extremly easy to use. Only two minutes are necessary to get the measurement.
µ-ROC Single-Shot Autocorrelator
μ-ROC takes the ROC concepts to its limit for the measurement of single-shot and repetitive autocorrelation traces in the smallest housing footprint ever.
MS-ROC Multi-Shot Autocorrelator
A multi-shot autocorrelator is suitable to characterize repetitive pulses and is based on second order scanning autocorrelation principle. Measures pulses with energy as low as 50 pJ.
