Abstract :
In this paper, we present a technically improved source of such rubidium resonant squeezed light. It uses a new pumping laser system and a technologically advanced locking scheme. To produce squeezed light, we use the proven technique of downconversion within a subthreshold OPO but with one distinct difference: our OPO is not pumped by a Ti:Sapphire laser, but by a diode laser system. This system consists of an external-cavity diode laser which is further amplified by an optical tapered amplifier and then frequency doubled in a LBO doubling cavity.
