MS-ROC stands for Multi-Shot Row Optical Correlator. The MS-ROC allows the measurement of autocorrelation traces. It is based on second harmonic generation, making it reliable and compact. It has been specially developed for sources with sub-nJ energy per pulse. It allows the measurement of pulses from 50 fs to 40 ps in the standard version. With its high scan speed, real-time operations is possible for measurement and optimization. The MS-ROC-LP can perform scan at 130 ps/s, making it the fastest scanning autocorrelator on the market. Also, the MS-ROC-SP allows the measurement of both ultra-short and long pulses thanks to its dual-mode (standard mode for pulse duration > 50 fs and fine-scan mode for pulse < 50 fs). Like every products, the MS-ROC is easy to install and use.

3 Those values give an order of magnitude. The exact sensitivity depends on many parameters (pulse duration, beam profile, wavelength…)
Measurement of few cycle pulses
On the top, the raw image of the spatially resolved autocorrelation trace.
At the bottom, the analysed autocorrelation trace integrated over the spatial coordinate. The experimental data (in red) are fitted by a Gaussian function (in blue). The full width at half maximum of the autocorrelation trace is 8.3 fs. The corresponding Gaussian pulse duration is 5.9 fs.
Measurement of low energy pulses
The average power used for the measurement was with only 20 mW at 62 MHz repetition rate. It means that in this conditions 0.3 nJ per pulse was enough to get a clean measurement. At the buttom, the raw image of the spatially resolved autocorrelation trace.
On the top, the analysed autocorrelation trace integrated over the spatial coordinate. The experimental data (in blue) are fitted by a Gaussian function (in red). The full width at half maximum of the autocorrelation trace is 30.4 fs for a Gaussian pulse duration of 21.5 fs.
