Abstract/Description:
Intensity auto correlator is device to measure pulse widths of ultrashort pulses on the order of picosecondsand femtoseconds. I have built an in-house, compact, portable, industry standard intensityauto correlator for measuring ultrashort pulse-widths. My device is suitable for pulse-widthsfrom 500 ps to 50 fs. The impetus for developing this instrument stemmed from our developmentof a multicore-fiber laser for high power laser applications, which also produces very short pulsesthat cannot be measured with an oscilloscope. As techniques for measuring short pulse-widthshave been well studied, what made my journey exciting was the process of taking an idea and realizinga successful, cost-efficient device. In this study, I have analyzed a Q-switched laser and mymeasured pulse-width matched the theoretical value previously calculated. I have also analyzedour mode-locked multicore fiber laser and results were encouraging. The notion to build one intensityautocorrelator was based on our labs future work, which was with modelocked multicore fiberlaser, which at the moment is giving pulses on order of nanoseconds. Dr. Axel Schulzgen gavethe responsibility to build an intensity autocorrelator on my shoulders. As, Intensity autocorrelatorshave been around for long time, he encouraged me to make one in house, compact, portableintensity autocorrelator which measures pulse widths of 50 fs up to 500 ps quite easily.
