A·P·E offers a choice of solutions for ultrafast pulse measurements. Each is tailored to your type of laser system, with a wealth of innovations for greater accuracy and user simplicity.
From material processing to scientific and medical base research, ultrafast laser systems are used in many areas of their high peak intensity and extremely short pulse width. One relevant area of application is time resolved spectroscopy. The pulse width is a critical factor for the adjustment of these laser systems and the characterization of experiments. A∙P∙E autocorrelators measure this parameter from 10 fs ... 500 ps for almost any wavelength range.
The autocorrelator pulseCheck USB 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 using different Optics Sets1), which can be upgraded in the field.
The pulseCheck USB with pulseLink controller combines the standard pulseCheck optical head with the new pulseLink controller replacing the standard control unit of the pulseCheck. It controls the measuring process, while being connected via USB to the Control Software running on the customer’s computer.
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 digitization and fast processing, the pulseLink provides the measured autocorrelation function and pulse width data at a high refresh rate and with a very high precision.
Furthermore the center wavelength 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 lasers.
The included Control Software allows for easy data export for further analysis.
