Authors demonstrate the use of low-gain optical parametric amplification (OPA) as a means of improving temporal
contrast to a detection-limited level 10−10. 250 J, 500 fs pulses of 1053 nm are frequency doubled and
subsequently restored to the original wavelength by OPA with >10% efficiency.

Author used Rincon third-order autocorrelator to measure the temporal contrast. (full article)

Rincon brochure - Rincon manual - Rincon software - Example of the measurement obtained

Third-order cross-correlator RINCON is a device developed for measuring and determining pulse pedestal, pre- and post-pulses and amplified spontaneous
emission in a high dynamic range. It is based on third-order cross-correlation technique and provides information about the cross-correlation function of pulse
intensity in fs scale.

Rincon Third Order Cross-Correlator (TOCC)

Each Rincon is optimized for customer laser system and required range of measurements.
The complete setup geometry, dimensions of non-linear crystals and some essential optics are all function of laser parameters and user-chosen tradeoffs between sensitivity, time resolution, time window, overall size etc.

We need the following information to set the tradeoffs and get all critical data necessary for the design which is optimized for your system:
1. What is wavelength of you laser system?
2. What is the repetition rate?
3. What is the normal pulse energy and beam diameter?
4. Is the laser pulse chirped?
5. What is the spectral bandwidth?
6. What is the pulsewidth?
7a. What is the expected (or estimated) contrast ratio as a function of delay from peak
7b. What is the minimum necessary contrast ratio as a function of delay from peak
8. What is beam quality (i.e. beam divergence relative to diffraction-limited one)
 

Rincon third-order cross correlator (TOCC). Rincon has been 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 (ASE) in femtosecond systems.

The third order cross-correlator Rincon has been 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 (ASE) 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.
Cross-correlator includes opto-mechanical assembly and electronics with USB interface. System is easy to operate and includes a full set of user friendly software tools for data collection and analysis.
