Rincon Cross-Correlator Pulse Profiling System

Del Mar Photonics

OVERVIEW

How good is the output from your femtosecond laser? The new third-order cross-correlator was specifically developed for measuring a wide array of output parameters from ultrafast laser systems including: contrast ratio of laser pulses, determining pulse pedestal, pre- and post-pulses, and amplified spontaneous emission in femtosecond systems. It also provides information about the third-order cross-correlation function of pulse intensity on a femtosecond scale and can be used for alignment of high power femtosecond lasers. A portion of the input pulse is converted to the second harmonic (SH) with a nonlinear crystal. A dichroic mirror reflects the SH and transmits the fundamental thus splitting the beam into the two arms of the crosscorrelator. The fundamental beam arm includes a retro reflector and delay-line. After passing through the delay-line the fundamental is recombined with the SH and focused into a DKDP or BBO crystal (depending on the input pulse wavelength). Mixing the fundamental and SH pulses in the nonlinear crystal produces non-collinear third harmonic generation (TH). By filtering out the fundamental and SH frequencies, the TH can be isolated. Measuring the TH signal as a function of the optical delay between the fundamental and SH pulses gives the third order cross correlation function.
