| The remaining portion is passed through a fixed λ/2 waveplate and PBS to split off the pump beam from the probe beam. The pump beam is directed to the Output Optics assembly where it is combined with the probe beam on a PBS in a counter-propagating configuration. The pump beam is dumped through the reflection port of the PBS that separated the pump and probe and terminates on the wall of the housing. | The remaining portion is passed through a fixed λ/2 waveplate and PBS to split off the pump beam from the probe beam.
