pulseCheck USB

Request a quotation

The pulseCheck USB autocorrelator is a versatile instrument for measuring the pulse width of different fs and ps laser systems, with the ability to cover a broad wavelength range, which can be upgraded in the field.

Combining the standard pulseCheck optical head with the new pulseLink controller, the pulseCheck USB allows for software control of the optical head from the user's PC. Enabled by a special scanner design and a real-time position measurement system, the instrument offers a linear time scale and different factory calibrated scan ranges.

In combination with a high resolution digitizing and fast processing, pulseLink provides the measured autocorrelation function and pulse width data at a high update rate, and with high precision. The center wavelangth of the input laser beam is derived from the interferometric autocorrelation data. Using an external trigger, the measuring process is also optimized for the measurement of low repetition rate laser.
