Description
Yb-doped large mode area tapered PM optical fiber
Developed by our key partner INO, the Yb-MCOF-35/250-56/400-07-2.2-T0.7-PM is a tapered fiber designed for an output M² lower than 1.2, making it the perfect choice for high power pulsed applications requiring superior beam quality. It features a confined core for selective gain amplification of the fundamental mode, and a patented depressed-cladding design for enhanced suppression of higher order modes. This tapered fiber has a linear absorption of 2.2 dB/m @ 915 nm and an output core diameter of 56 µm.

- Effective mode area ~ 1000 µm2
- Low photodarkening
- Polarization-maintaining fiber
- Depressed cladding for enhanced higher-order mode filtering
- Confined core for selective amplification of the fundamental mode
Applications
- High Peak Power Lasers
- Ultrafast Amplifiers
- Frequency Conversion
