We describe a single stage 50‐Ω, 10× resistive attenuator with a rise time less than 100 ps used to measure 20‐kV, 2‐ns pulses, driving an electro‐optic shutter in a 50‐J, CO2 laser system. An aqueous solution of aluminum nitrate is used as a resistive element. An axially symmetric shielded structure allows cascade operation of more units. Practical design parameters for a given matched impedance and attenuation as well as calibration procedures are reported.
