Laser polarization

    Hi,
    if the laser emits polarized light, then why we use polarizer infront of laser?

    Can you mention specific application? As far as my experience with laser is concerned, we never really use a linear polarizer in front of a laser with already good linear polarization quality as that will only reduce the intensity due to absorption and reflection.
