PM-TSF-5/125, Panda-Type Tm-Doped Select Cutoff PM Optical Fiber
These single clad, small core diameter fibers feature a highly Tm-doped core region (~7% Tm). They are ideally suited for core pumping, enabling very short laser cavities required for ultra-fast fiber lasers with high slope efficiency under resonant pumping. The 5 µm core diameter with its 0.24 NA offers superior single-mode operation and excellent bending performance.
Features
- Small diameter Tm-doped core design - Robust single mode beam quality
- Flexible design - May be pumped with 793 nm diodes or resonantly pumped using a fiber laser
- High pump absorption - Short fiber length enables efficient lasing in the ~2 µm window
- High Tm concentration core - Facilitates access to shorter lasing wavelengths below 1900 nm
- Clean room draw - Eliminates coating “hot spots”
- RoHS compliant
Applications
- Low to mid-power CW and pulsed Eye-Safe (~2 µm) lasers and amplifiers
- Ultra-fast (~2 µm) fiber lasers
- Military and commercial LIDAR
- 2 µm fiber lasers for pumping crystal lasers
