چکیده

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 thermal regeneration grating fabrication process opens new possibilities to design and to implement fiber laser sensors for extreme environments.

Short Cavity Erbium/Ytterbium Fiber Lasers Mode-Locked with a Saturable Bragg Reflector

We present short cavity erbium/ytterbium fiber lasers that are passively mode-locked with a saturable Bragg reflector. The lasers produce sub-500-fs pulses at fundamental cavity repetition rates as high as 300 MHz. Stable passive harmonic operation increases the repetition rate to 2.0 GHz. The mode-locking mechanism in both the normal and anomalous group velocity dispersion regimes is investiga...

Wafer bonded 1.55 mm vertical-cavity lasers with continuous-wave operation up to 105°C

Vertical cavity surface emitting lasers ~VCSELs! emitting in the 1.55 mm wavelength region are attractive sources for optical networks. Advantages of VCSELs include low power consumption, efficient fiber coupling, and high volume, low cost manufacturing. Transmission at 1.55 mm allows for long distance transmission over optical fiber with low attenuation and dispersion. The main limitation to r...

Efficient Single Frequency Fibre Lasers Using Novel Photosensitive ErYYb Optical Fibres

Boron and germanium doped highly photosensitive cladding is used in a novel design to achieve photosensitive Er/Yb doped fibres, enabling short strong gratings (length = 1 cm, reflectivity > 99%) to be written without hydrogenation. The high absorption at 980 nm in Er/Yb fibres allows efficient pump absorption over a short device length, ideal for achieving highly efficient single frequency fib...

Formation and Applications of the Secondary Fiber Bragg Grating †

Being one of the most proven fiber optic devices, the fiber Bragg grating has developed continually to extend its applications, particularly in extreme environments. Accompanying the growth of Type-IIa Bragg gratings in some active fibers, a new resonance appears at the shorter wavelength. This new type of grating was named "secondary Bragg grating" (SBG). This paper describes the formation and...
