Er:YAG Laser Rod, Fotona

Er:YAG Laser Rod for Fotona Dynamis XS, SP, TimeWalker, Spectro

• Manufactured by: Northrop Grumman, USA
• Rod material: Er:YAG
• Condition: Brand new

This Er:YAG Laser Rod for Fotona acts as the gain medium for 2940 nm laser generation in Fotona Er:YAG systems. The 2940 nm Er:YAG wavelength is strongly absorbed by water, which makes it ideal for precise, layer-by-layer skin ablation with very little thermal spread — the basis for Fotona's ablative resurfacing and Er:YAG treatment modes. This rod supports stable pulse formation, consistent energy output, and reliable 2940 nm performance during professional aesthetic treatments.

This laser rod is manufactured by Northrop Grumman, USA, a reputable manufacturer of high-quality laser crystal components. In Fotona service work, rod quality directly affects Er:YAG output stability, ablation precision, and pulse consistency at the treatment handpiece.

Many Fotona platforms combine a 2940 nm Er:YAG laser with a 1064 nm Nd:YAG laser in a single dual-wavelength system. This page is for the Er:YAG Laser Rod used in the 2940 nm Er:YAG cavity — a separate service area from the Nd:YAG cavity. A worn, damaged, or internally defective Er:YAG rod can lead to reduced 2940 nm output, unstable energy delivery, poor ablation consistency, burn marks, or laser-head service issues. Replacing it with the correct Er:YAG rod helps restore reliable 2940 nm performance after cavity service or laser-head repair.
