Alexandrite rod for laser machine is DEKA Motus AX before repair

Описание: Alexandrite rod for laser machine is DEKA Motus AX before repair
Del Mar Photonics offers both a new replacement Alexandrite rod and refurbishment of an existing Alexandrite rod.
The refurbishment service includes precision repolishing and recoating, provided that the rod is not physically damaged. This allows restoration of optical performance and extension of the rod’s service life as a cost-effective alternative to full replacement.

The DEKA Motus AX is a high-performance medical laser system widely used in dermatology and aesthetic medicine, particularly for hair removal and pigmented lesion treatments. It is based on an Alexandrite laser operating at 755 nm, a wavelength known for its strong absorption in melanin and excellent clinical efficacy across a wide range of skin types when properly configured and maintained.

At the core of the DEKA Motus AX system is the Alexandrite laser rod. This crystal acts as the active gain medium, converting pump energy into coherent laser output. The optical quality, surface polish, coatings, and crystal homogeneity of the Alexandrite rod directly determine the system’s output power, beam quality, stability, and overall lifetime. Over time, due to high optical fluence, thermal cycling, and normal wear, the rod may degrade, leading to reduced performance, unstable operation, or complete laser failure.

Common symptoms of Alexandrite rod degradation in the DEKA Motus AX include reduced output energy, inconsistent pulse behavior, higher lasing thresholds, overheating, or visible coating damage. In such cases, professional repair is required to restore the system to factory-level performance.

DEKA Motus AX repair typically involves either replacement or refurbishment of the Alexandrite rod. Replacement rods are manufactured to match the original specifications exactly, including crystal dimensions, doping level, crystallographic orientation, and optical coatings. This ensures full compatibility with the original resonator design and preserves the laser’s clinical performance and safety parameters.

When the rod is not physically damaged, refurbishment is often a cost-effective alternative. This process may include precision repolishing of optical surfaces and application of new high-damage-threshold anti-reflection coatings optimized for 755 nm operation. Proper refurbishment can significantly extend the lifetime of the Alexandrite rod and restore stable laser output while minimizing system downtime.

Professional Alexandrite rod repair or replacement for the DEKA Motus AX requires strict optical tolerances, cleanroom-level handling, and experience with high-power solid-state medical lasers. Incorrect polishing, coating mismatch, or dimensional deviation can lead to poor efficiency, optical damage, or irreversible resonator misalignment.

A correctly serviced DEKA Motus AX with a refurbished or replacement Alexandrite rod can return to near-original performance, providing reliable operation, consistent energy delivery, and long-term stability. This ensures continued clinical effectiveness while protecting the investment in the laser system.

For clinics and service providers, timely Alexandrite rod repair is essential to minimize downtime, maintain treatment quality, and ensure patient safety. Whether opting for full rod replacement or refurbishment, using components that meet original optical and mechanical specifications is critical for achieving optimal results.
