High dynamic high power laser contrast measurement


Ultra-high Contrast Third-order Autocorrelator


Our third-order autocorrelator TUNDRA® is a highly sensitive diagnostic tool to measure laser pulse contrast. After further development, the device can measure up to 14 orders of magnitude of dynamic range, allowing characterization of background and detection of the tiniest pre- and post-pulse replicas from the world's most powerful lasers. The autocorrelator utilizes all-reflective components, ensuring accurate correlation traces without measurement artifacts. Unlike second-order autocorrelators, the device can distinguish pre- and post-pulses due to the third-harmonic nature of the signal. Use TUNDRA® to achieve state-of-the-art characterization of ultrashort and intense laser pulses.
