Abstract
A compact device based on a modified Mach-Zehnder interferometer was built to monitor the output of a Ti:Al2O3 femtosecond oscillator. Once aligned it is insensitive to the input beam position and direction. With a single 9 V power supply the autocorrelation of interferometric resolution is obtained to be watched directly on the oscilloscope.
