Autocorrelator - Multi Shot

Overview Specification and Software Related Products Order Now!

The Multi-Shot Row Optical Correlator (MS-ROC) autocorrelator allows the user to measure autocorrelation traces. This is possible due to the principle of second harmonic generation.

The autocorrelator is a reliable and compact instrument that has been specificially manufactured for sources with sub-nJ energy per pulse. It also allows for the measurement of pulses from 50fs to 40ps.

See the specification sheet for the full list of specifications of the various models

Defining Features

• Ultra simple alignment (2 min to setup)

• Large pulse duration measurement range (from 5 fs to 80 ps)

• High sensitivity (sub-nJ pulse)

• User-friendly and powerful software (STAR : Software Technology for Acquisition and retrieval)

• Broad available spectral range

• Fiber connector available (FC/APC, FC/PC)

Model Highlights

• The MS-ROC-LP can perform scan at 130 ps/s, making it the fastest scanning autocorrelator on the market.

• 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).

Accessories and Add-Ons

The MS-ROC comes equipped with various options to enhance the user experience.

Options	Desciption
Additional crystals	The default MS-ROC configuration includes one crystal. To extend the wavelength range of the device, additional plug&play crystals can be ordered and swapped within the system in seconds
Fiber input connector	Plug play collimation module with fiber connector. Can be mounted on the MS-ROC to easily switch the input from free-space to fiber. No alignment required.
Low energy	Internal module to increase the sensitivity of the MS-ROC when the laser power is too weak
Low repetition rate	Synchronization mode to be used when the laser repetition rate is low. Mandatory for 100 Hz and lower, recommended from below 500 Hz
Phase matching	Default MS-ROC configuration works for a given central wavelength. Phase matching allows tuning the SHG crystal to measure different central wavelengths with the best SNR
