1.1 Mirror Surface to Bulk Mirror Delta (ΔTMIRROR_SURFACE-TO-BULK_MIRROR)

The bulk mirror to mirror surface temperature rise represents the temperature rise of the top of the mirror (surface) to the bulk mirror temperature. It is possible to generate a significant temperature rise above the bulk mirror temperature through the thickness of the mirror if the pulse duration is short enough and the optical pulse power incident on that mirror is high enough. An example of this calculation is shown in Section 2.1.
