Abstract
We demonstrate a diode-laser-pumped system for generation of quadrature squeezing and polarization squeezing. Due to their excess phase noise, diode lasers are challenging to use in phase-sensitive quantum optics experiments such as quadrature squeezing. The system we present overcomes the phase noise of the diode laser through a combination of active stabilization and appropriate delays in the local oscillator beam. The generated light is resonant to the rubidium $D1$ transition at $795\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ and thus can be readily used for quantum memory experiments.
