Abstract

We report a rapid scanning optical delay line scannable over an interval more than 1000 times the input pulse width, a range is more than 20 times greater than obtained with of our previously reported¹ device based on femtosecond pulse shaping techniques.^2,3 We now scan 90 femtosecond pulses over more than 100 ps range. The large time window and the capability for high speed scanning makes this device an attractive tool for both autocorrelation displays and high speed data acquisition^4,5 in pump-probe experiments. Additionally, new insight is gained on the nature of the maximum time window in femtosecond pulse shaping.
