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.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThis laser rod is manufactured by \u003cstrong\u003eNorthrop Grumman, USA\u003c\/strong\u003e, 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.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eMany Fotona platforms combine a \u003cstrong\u003e2940 nm Er:YAG\u003c\/strong\u003e laser with a \u003cstrong\u003e1064 nm Nd:YAG\u003c\/strong\u003e laser in a single dual-wavelength system. This page is for the \u003cstrong\u003eEr:YAG Laser Rod\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003e\u003cspan\u003eTechnical Details:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-spread=\"false\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eProduct type:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Laser Rod\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eRod material:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Er:YAG\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eManufacturer reference:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Northrop Grumman, USA\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eApplication area:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Fotona Er:YAG laser cavity\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eFunction:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Acts as the laser gain medium for 2940 nm Er:YAG energy generation\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eCommon replacement reasons:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e reduced output, unstable energy, visible rod damage, internal defects, burn marks, cavity service, laser-head repair, or end-of-life performance drop\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eCondition:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Brand new replacement part\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eThis part is compatible with the following devices:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFotona XS Dynamis\u003c\/li\u003e\n\u003cli\u003eFotona SP Dynamis\u003c\/li\u003e\n\u003cli\u003eFotona SP Dynamis Pro\u003c\/li\u003e\n\u003cli\u003eFotona TimeWalker\u003c\/li\u003e\n\u003cli\u003eFotona Smooth\u003c\/li\u003e\n\u003cli\u003eFotona SP Spectro\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAt LaserX Parts, we carefully select and quality-check every product to ensure only premium-quality spare parts reach our customers.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.8em;\"\u003eLaserX Parts is an independent supplier of spare parts for professional laser and aesthetic devices.
