Abstract:
1. A dual pulsed light generation apparatus, comprising: a polarization beam splitter (PBS), having a first plane, a second plane, and a dividing interface located between the first plane and the second plane in the transmission path of an incident pulsed beam, for dividing the incident pulsed beam into a first polarization pulsed beam and a second polarization pulsed beam while enabling the first polarization pulsed beam to be reflected by the dividing interface and thus travel passing through the first plane, and the second polarization pulsed beam to travel passing through the dividing interface; a first polarization reflector, disposed opposite to the first plane for transforming the first polarization pulsed beam into a third polarization pulsed beam capable of passing through the dividing interface; a half wave plate, disposed next to the PBS at a position on the transmission path of the incident pulsed beam, such that the half wave plate adjusts the polarization of an initial pulsed beam transforming the initial pulsed beam into the incident pulse beam containing both first polarization light and second polarization light; and a second polarization reflector, disposed opposite to the second plane.
