Abstract:
1. A coherence remover, comprising: a first mirror; a second mirror coupled to the first mirror; a first polarizing beam splitter configured to receive an input beam and to pass the input beam having a first polarization such that the input beam is incident on the first and second mirrors, wherein the first and second mirrors comprise a first reflective surface normal to an axis of the input beam, a first quarter wave plate configured to alter a polarization state of the first output beam, a third mirror, separate from the first and second coupled mirrors; a fourth mirror, coupled to the third mirror, a second polarizing beam splitter configured to receive the altered first output beam and to reflect the altered first output beam having the second polarization such that the altered first output beam is incident on the third and fourth mirrors, wherein the third and fourth mirrors comprise a second reflective surface normal to an axis of the altered first output beam, a second quarter wave plate configured to alter a polarization state of the second output beam,
