Synthetic Ruby Rods for Laser Applications – Precision Cr:Al₂O₃, Up to 200 mm

描述

These synthetic ruby laser rods are manufactured from single-crystal chromium-doped aluminum oxide (Cr:Al₂O₃) grown by the Verneuil (Flame Fusion) process. This crystal growth method has been extensively used for ruby laser materials and provides reproducible crystal quality, stable optical characteristics, and reliable laser performance.

The rods are designed for use as the active gain medium in pulsed ruby laser systems operating at 694.3 nm. Controlled chromium concentration and uniform crystal structure enable consistent fluorescence behavior and predictable laser output. Due to chromium doping and crystal growth stress characteristics, ruby crystals generally exhibit size limitations compared with undoped sapphire; nevertheless, rod lengths up to 200 mm can be supplied depending on diameter and specification.

Each laser rod is precision fabricated with optical-grade polishing and tight geometric control of the end faces. Custom dimensions, tolerances, and surface finishes can be provided in accordance with customer drawings or application requirements.
