Single crystals of CuCl at 8 K were excited with the low‐intensity frequency‐doubled output of an actively mode‐locked R6‐G dye laser. The time dependence of the bound exciton luminescence was measured directly by a synchronously operating electron‐optical streak camera accumulating data at the dye laser repetition rate of 82 MHz. The instrumental time resolution was ∼25 ps. The observed bound exciton lifetime for theIline (3898 A˚) was typically ∼130 ps with a formation time of less than 10 ps.
