Alexandrite HR Mirror, DEKA Synchro Replay 2.4.2 / 3.4 | 080201078

Alexandrite HR Mirror for DEKA Synchro Replay 2.4.2 / 3.4

DEKA Part Number Reference: 080201078

This Alexandrite HR Mirror for DEKA Synchro Replay 2.4.2 / 3.4 is used as the high-reflector mirror in the 755 nm Alexandrite laser resonator. Also known as a rear mirror, this optic reflects laser energy back through the cavity to support proper energy build-up before output is released through the OC mirror.

For DEKA Synchro Replay 2.4.2 / 3.4 systems, the HR mirror should be matched to the correct resonator version. This mirror should not be confused with the Alexandrite HR Mirror used in earlier DEKA Synchro Replay 0.7 / 1.7 models, as they are different mirrors and are not intended to be used interchangeably.

The HR mirror plays a different role from the OC mirror. While the OC mirror controls laser output coupling, the HR mirror supports internal cavity feedback and reflection stability. Damage, contamination, or coating deterioration on this rear mirror can affect energy build-up, calibration behavior, and Alexandrite output consistency.

During laser-head service, technicians should inspect the HR mirror together with the OC mirror, Alexandrite rod, flash lamp, reflector, cooling condition, and optical alignment. Installing the correct HR mirror helps restore proper rear-cavity reflection and supports stable DEKA Synchro Replay performance after resonator service.
