A heat assisted magnetic recording (HAMR) writer is described. The HAMR writer includes a laser, a polarization rotation plate and a HAMR transducer. The laser provides energy having a first polarization state. The polarization rotation is plate optically coupled with the laser and changes the first polarization state to a second polarization state. The transducer has an ABS, a waveguide, a main pole, at least one coil and a near-field transducer (NFT). The polarization rotation plate is between the transducer and the laser. The waveguide is optically coupled with the laser through the polarization rotation plate and directs the energy from the polarization rotation plate toward the ABS. The NFT focuses the energy onto a media. The NFT is optically coupled with the waveguide and receives energy having a third polarization state. The main pole writes to the media and is energized by the coil(s).
