Description
Designed for high-power 2 µm laser systems, this polarization-maintaining (PM) double-clad thulium-doped fiber features a non-pedestal core architecture, high briefringence, and optimized 790 nm cladding absorption for outsanding efficiency and reliability. The non-pedestal design eliminates parasitic mode guidance, reduces splice sensitivity, and enchances polarization stability, delivering excellent beam quality and a high polarization extinction ratio (PER). Its optimized core composition maximizes cross-relaxation efficiency while supporting robust power scaling.
Features & Benefits
- Single-mode operation at 1940 nm.
- No-pedestal design prevents parasitic modes.
- Easier integration and lower splice losses compared to pedestal-based designs.
- Superior polarization maintenance and higher polarization extinction ratio (PER).
- Optimized core enables efficient two-for-one cross-relaxation at 2 µm.
Applications
- High-power PM CW and pulsed fiber lasers
- Narrow-linewidth and single-frequency lasers
- Coherent beam combining (CBC)
- Coherent Doppler/FMCW LIDAR
- Pump source for PM Ho-doped fibers
- Telecom and coherent optical communications
- Medical laser systems
