Description
Discover the exceptional capabilities of our cutting-edge third-order cross-correlator, meticulously engineered to deliver precise measurements of output parameters from ultrafast laser systems. This advanced instrument is designed to evaluate the contrast ratio of laser pulses, identify pulse pedestals, and detect pre- and post-pulses as well as amplified spontaneous emission in femtosecond systems. It excels in providing detailed insights into the third-order cross-correlation function of pulse intensity on a femtosecond scale, making it an indispensable tool for aligning high-power femtosecond lasers.
The operational mechanism involves converting a portion of the input pulse into the second harmonic (SH) using a nonlinear crystal. A dichroic mirror then separates the SH from the fundamental, directing them into two distinct arms of the cross-correlator. The fundamental beam arm incorporates a retro reflector and a delay-line, which, after processing, recombines with the SH in a DKDP or BBO crystal, depending on the input pulse wavelength. This process results in non-collinear third harmonic generation (TH). By filtering out the fundamental and SH frequencies, the TH is isolated, allowing for precise measurement of the third-order cross-correlation function based on the optical delay between the fundamental and SH pulses.
The cross-correlator is expertly crafted to assess the complete range of outputs from amplified femtosecond laser systems. It offers high temporal resolution over an extended window, close to 1 ns, revealing pulse features typically overlooked. This comprehensive analysis provides users with a detailed and complete picture of the quality and stability of their femtosecond laser system's output pulse parameters.
Our cross-correlator system includes an opto-mechanical assembly and electronics that connect via a USB interface to a PC, ensuring ease of operation. It comes equipped with a full suite of user-friendly software tools for efficient data collection and analysis, making it an ideal choice for both novice and experienced users seeking to enhance their laser system's performance.

Frequently Asked Questions
The Rincon Cross-Correlator Pulse Profiling System is 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.
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 cross-correlator. 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.
The Rincon Cross-Correlator Pulse Profiling System 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.
The Rincon Cross-Correlator Pulse Profiling System has high temporal resolution over a long (close to 1 ns) window, which shows pulse features that are usually missed, giving the user a detailed and complete picture of the quality and stability of the output pulse parameters of their femtosecond laser system.
