1945 The Services Electronics Research Laboratory (SERL) was established at Harlow and Baldock, as the research department for contract valve development.
1945-50: SERL concentrated on:
1950s: SERL developed:
1962 SERL began work on the "Optical Maser", and later Lasers, initially leading to the He‐Ne ring laser proposed for inertial navigation systems.
1964 SERL started work on the low‐noise parametric amplifier, which became widely used in satellite communication and radar systems. Also, began work on pulsed excitation of gas lasers, leading to the discovery of the high efficiency CO2 laser.
1976 The Services Electronics Research Laboratory at Baldock moved to Malvern and was merged with other laboratories including the Royal Radar Establishment to form the Royal Signals and Radar Establishment.
