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