Alexandrite HR Mirror, Quanta System | OBM000184, OBM001220

Alexandrite HR Mirror for Quanta System Duetto, Domino, Light, Q-Plus

Quanta System Part Number Reference: OBM000184 / OBM001220

This Alexandrite HR Mirror for Quanta System laser devices is used as the high-reflector mirror in the Alexandrite laser resonator. Also known as a rear mirror, this optic helps maintain strong cavity feedback so the Alexandrite section can build stable laser energy before output is released through the OC mirror.

Unlike an output coupler, the HR mirror is designed to keep laser energy reflected inside the resonator. Its reflective coating condition is important for maintaining proper feedback, cavity efficiency, and stable 755 nm Alexandrite performance during repeated laser operation.

A damaged, contaminated, or degraded HR mirror can affect the resonator even if other components appear normal. Service symptoms may include reduced energy, unstable output, difficult calibration, poor beam behavior, or increased sensitivity after laser-head work.

During Alexandrite cavity service, technicians should inspect the HR mirror together with the OC mirror, laser rod, flash lamp, reflector, cooling condition, and optical alignment. Replacing a worn or damaged Alexandrite HR mirror helps restore the rear-reflection function of the resonator and supports reliable laser performance after service.
