Popis: Intense photoexcitation of GaAs by picosecond laser pulses creates a superdense electron‐hole plasma (∼1020 cm−3) which sustains laser action from 8900 A in the IR to 7700 A in the visible. Tunable picosecond laser pulses are obtained by moving a slightly wedged ultrashort cavity in the focus of the pump laser pulse.
