    "abstract": "We report on the generation of more than 5 dB of vacuum squeezed light at the\nRubidium D1 line (795 nm) using periodically poled KTiOPO$_{4}$ (PPKTP) in an\noptical parametric oscillator. We demonstrate squeezing at low sideband\nfrequencies, making this source of non-classical light compatible with\nbandwidth limited atom optics experiments. When PPKTP is operated as a\nparametric amplifier, we show a noise reduction of 4 dB stably locked within\nthe 150 kHz-500 kHz frequency range. This matches the bandwidth of\nElectromagnetically Induced Transparency (EIT) in Rubidium hot vapour cells\nunder the condition of large information delay.",
