These single clad, small core diameter fiber features a very highly Tm-doped core region (~7% Tm). They are ideally suited for core pumping, enabling very short laser cavities required in producing ultra-fast fiber lasers with high slope efficiency under resonant pumping. The 5 µm core diameter with its 0.24 NA, together, offer superior single-mode operation and excellent bending performance.

The PM variety is designed with the PANDA style stress structure which delivers linearly-polarized light; the non-PM version is available for applications that do not require a polarized signal

Details

Features & Benefits

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, 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”

Typical 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
