Which optical component has the capability of changing the intensity of a CW laser without any changes in its polarization or any distortion?

A simple idea to change a -fixed intensity- CW laser output intensity is to utilize a polarizer and thus changing polarization will lead to change in its output intensity. If someone needs to keep...
