The IO work on the Faraday Isolator on the PSL/IO table is finished, so today I started the transition to low-power mode.

The high-power oscillator was shut down (to conserve pump diode lifetime).

The PMC modematching lenses have not been moved yet and the alignment into the PMC has not been adjusted.

For now, the front-end internal and external (manual, mechanical) shutters have been closed for installation of the beam tube between the Laser Area Enclosure and the HAM1 chamber.

Tomorrow, we plan to complete the transition to low-power mode.
