Abstract :
Amplification has been measured in a DH GaAs regenerative amplifier. Both strong and weak signal regimes have been studied with measured gains as large as 170. A regime of coupling between the regenerative amplifier and laser source is also identified, resulting in a lowering of the threshold of the regenerative amplifier in the presence of an incident laser signal. Comparisons between the experimental results and the theoretical models show good agreement.
