We report experimental evidence of the coupling between the pump diode current and the output differential phase in a two-axis two-polarization dual-frequency solid-state laser. The effect has the same transfer function shape as that for a pump current to output power one, suggesting a pump AM/laser PM coupling in the laser medium. We report that the pump amplitude noise is negligible in the laser differential phase noise assuming a linear coupling. (C) 2016 Optical Society of America
