Due to their enormous power, terawatt and petawatt laser pulses may reach ionization threshold values of 1010 W/cm2 already several pico- or nanoseconds before the main laser pulse by either poor amplified spontaneous emission (ASE) levels or parasitic pre-pulses in an uncontrolled manner.
In order to avoid these deleterious effects, one needs a way to characterize the temporal intensity profile and the quality of the laser pulses with extremely high sensitivity. To achieve this, UltraFast Innovations (UFI®) developed TUNDRA++, the latest generation of UFI’s popular third-order autocorrelator TUNDRA®. Thanks to implementing an innovative concept, TUNDRA++ is capable of measuring up to 14 orders of magnitude dynamic range, making it ideal for pulse contrast measurements of the most powerful femtosecond laser systems in the world.
