In contrast to second-order autocorrelators, pre- and post-pulses can be distinguished due to the third-harmonic nature of the signal. These features make our specialized fully-automated autocorrelator an invaluable tool for state-of-the-art contrast characterization of ultrashort and intense laser pulses.\u003c\/p\u003e\n\u003cp\u003eTUNDRA has been used to characterize some of the most powerful and unique terawatt- and petawatt-class laser systems in the world, including \u003cstrong\u003eATLAS\u003c\/strong\u003e (Garching, 50-250 TW), \u003cstrong\u003ePFS\u003c\/strong\u003e (MPQ, 100 TW), \u003cstrong\u003eSYLOS\u003c\/strong\u003e (ELI-ALPS), \u003cstrong\u003eAPOLLON\u003c\/strong\u003e (Palaiseau, up to 5 PW), \u003cstrong\u003ePHELIX\u003c\/strong\u003e (GSI, 500 TW), and \u003cstrong\u003eSALLE JAUNE\u003c\/strong\u003e (LOA, 200 TW).\u003c\/p\u003e\n\u003ch3\u003eKey Product Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUltra-sensitive pulse contrast measurement\u003c\/li\u003e\n\u003cli\u003eThree dynamic-range tiers: 10¹¹ (TUNDRA), 10¹² (TUNDRA+), up to 10¹⁴ (TUNDRA++)\u003c\/li\u003e\n\u003cli\u003eUp to 3.8 ns scan range — capture pre- and post-pulses across long delays\u003c\/li\u003e\n\u003cli\u003eNo ghost pulse artefacts (all-reflective design)\u003c\/li\u003e\n\u003cli\u003eEasy to set up and use — fully automated\u003c\/li\u003e\n\u003cli\u003eFull user-friendly software package\u003c\/li\u003e\n\u003cli\u003eCustomizable for laser specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAvailable Laser Types\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTi:Sa — 800 nm\u003c\/li\u003e\n\u003cli\u003eCr³⁺-based: 690-850 nm (e.g., ruby, alexandrite, colquiriite lasers)\u003c\/li\u003e\n\u003cli\u003eNd-based: 1053-1064 nm (e.g., Nd:YAG, Nd:YLF, Nd:Glass)\u003c\/li\u003e\n\u003cli\u003eYb-based: 1007-1079 nm (e.g., Yb:YAG, Yb:LuAG, Yb:YLF, Yb:KGW, Yb:CALGO, Nd:YAP)\u003c\/li\u003e\n\u003cli\u003eCustom wavelengths available upon request\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eReferences\u003c\/h3\u003e\n\u003col\u003e\u003cli\u003eV.
