Abstract

The dispersion-scan technique (d-scan) is a well-established technique for the measurement of ultrashort laser pulses. While a single-shot version of d-scan is relatively easy to implement for sub-10 fs laser pulses, this becomes increasingly difficult as the pulse duration increases due to the need for a larger dispersion range, which scales quadratically with the Fourier transform limit (FTL). Here, we present a solution using a grism (a combination of prism and grating) to measure tens of femtosecond pulses without modifying the principle of the single-shot d-scan. Our grism, made of a zinc sulfide prism and a transmission grating, achieves a dispersion range window of 3200 fs2. We demonstrate this new method, to our... (More)

The dispersion-scan technique (d-scan) is a well-established technique for the measurement of ultrashort laser pulses. While a single-shot version of d-scan is relatively easy to implement for sub-10 fs laser pulses, this becomes increasingly difficult as the pulse duration increases due to the need for a larger dispersion range, which scales quadratically with the Fourier transform limit (FTL). Here, we present a solution using a grism (a combination of prism and grating) to measure tens of femtosecond pulses without modifying the principle of the single-shot d-scan. Our grism, made of a zinc sulfide prism and a transmission grating, achieves a dispersion range window of 3200 fs2. We demonstrate this new method, to our knowledge, by characterizing pulses with an FTL of 25 fs and different spectral phases, comparing the results with a conventional d-scan.
