Paper Abstract

Polarization filtering in a laser mirror is achieved by means of a corrugation grating defined in the last high index layer of multilayer mirror based on a metal or metallized substrate. The grating couples the undesired TE polarization to a high order propagation mode of the metal based multilayer stack. The resulting dip in the TE spectral reflection curve is wide enough to cover the gain bandwidth of a Nd:YAG active medium. A technology trimming scheme is designed and demonstrated to shift the TE reflection dip to 1064 nm.
