Autocorrelator SSNA

Autocorrelator SSNA allows to display and to measure the temporal pulse shape of single ultrashort light pulse with duration from 50 fs to 40 ps.

The Autocorrelator SSNA is the nonlinear optical device, which will allow you to display and to measure in the real time the temporal pulse shape of single ultrashort light pulse with duration from 50 fs to 40 ps. The method used in the Autocorrelator SSNA is based on the noncollinear second harmonic (SH) generation, where the spatial distribution of the SH light contains information on the time behavior of the fundamental light pulse. This technique combines the zero background and the single-shot measurement capability. For immediate observation of pulse duration it is convenient to use the photodiode array.

The Autocorrelator SSNA can be used with many of today's ultrashort pulse lasers. The Autocorrelator SSNA can be constructed for temporal shape measurements of the pulses with duration down to 30 fs in spectral range from 523 nm to 1400 nm and with lower temporal resolution in spectral range up to 4000 nm.

Complete Registration System on CCPD Array for Autocorrelator SSNA
For immediate display of the single pulse autocorrelation function produced by Autocorrelator SSNA it is necessary to use a linear photodiode array or optical multichannel analyzer. Optical multichannel analyzer is expensive and so not available in many cases. Single pulse temporal shape with accuracy necessary for laser and compressor adjustment can be displayed on the oscilloscope using linear photodiode array in combine with Autocorrelator SSNA. We propose the complete registration system on the 1024 - element photodiode array with integrate sample - and - hold amplifier circuit board and power supply. The photodiode array with integrate sample - and - hold amplifier circuit board is placed in the box, which fits in the exit slit of the Autocorrelator SSNA. The spectral response of the photodiode array is in the spectral range 0.2 - 1.1 mm. The photodiode array is powered from power supply.
