The 1940 nm thulium fiber laser sits right at the water absorption peak, so energy is absorbed in a very shallow tissue layer: precise cutting and lithotripsy with low bleeding risk and minimal mucosal damage. The small-core fiber delivers high energy efficiently, making it an ideal partner for flexible endoscopy and minimally invasive laser surgery in veterinary patients.
Key Features
- 1940 nm wavelength at the water absorption peak – shallow penetration, precise ablation
- Fine-core fiber delivery for efficient, precise lithotripsy through endoscopes
- Low bleeding risk and shallow mucosal injury for safer cavity surgery
- Wide parameter range: pulse energy, pulse width and frequency freely adjustable
- Air-cooled – no external chiller needed
- Compact footprint, simple operation, two power models available
