Abstract: A novel tunable dual-wavelength thulium-doped fiber laser is demonstrated experimentally. The wavelength-tuning by employing a high birefringence fiber Bragg grating is proposed in 2-\(\mu \ ...

Abstract: In recent years, there is a growing interest to thulium (Tm) lasers operating at ~2.3 µm according ... reported on a continuous-wave (CW) Tm:KY 3 F 10 laser delivering 0.84 W at 2331-2346 nm ...
