Ultra-short distributed Bragg reflector fiber laser for sensing applications.
We present an ultra-short distributed Bragg reflector fiber laser written in Er/Yb co-doped fiber. The entire laser is only 8.4 mm in length. The lasing threshold is less than 1 mW. The optical signal-to-noise ratio of the laser output is better than 70 dB. The laser emits two orthogonal polarization modes and generates a beat signal with signal-to-noise ratio of approximately 70 dB and 3-dB li...
متن کاملThermo-optical Tuning of Erbium-Doped Fiber Ring Laser
A thermo-optically tunable multimode interference fiber laser is demonstrated. The laser emission can be easily tuned trough the C-band by simply changing the temperature around the multimode fiber liquid cladding of the filter. ©2011 Optical Society of America OCIS codes: (060.2410) Fibers, Erbium; (060.2310) Fiber Optics; (140.3600) Lasers Tunable; (060.4510) Optical communications
متن کاملResonant pumped erbium-doped waveguide lasers using distributed Bragg reflector cavities.
This Letter reports on an optical pumping scheme, termed resonant pumping, for an erbium-doped distributed feedback (DFB) waveguide laser. The scheme uses two mirrors on either side of the DFB laser, forming a pump cavity that recirculates the unabsorbed pump light. Symmetric distributed Bragg reflectors are used as the mirrors and are designed by matching the external and internal quality fact...
متن کاملS-band multiwavelength Brillouin/Raman distributed Bragg reflector fiber lasers.
A multiwavelength Brillouin/Raman distributed Bragg reflector fiber laser operating in the S-band region is proposed and demonstrated. The laser uses a 7.7 km long dispersion-shifted fiber with an effective mode area of 15 μm(2) as the Brillouin and Raman gain media simultaneously. Two 1420 nm laser diodes with a combined power of 372 mW are used as pump sources, while a fiber Bragg grating wit...
متن کاملRegenerated distributed Bragg reflector fiber lasers for high-temperature operation.
This Letter presents distributed Bragg reflector (DBR) fiber lasers for high-temperature operation at 750°C. Thermally regenerated fiber gratings were used as the feedback elements to construct an erbium-doped DBR fiber laser. The output power of the fiber laser can reach 1 mW at all operating temperatures. The output power fluctuation tested at 750°C was 1.06% over a period of 7 hours. The the...
