A femtosecond laser inscription technique is proposed for the fabrication of a fiber grating laser directly into a nonphotosensitive gain fiber, A distributed Bragg reflector fiber grating laser is realized in a conventional, untreated Er: Yb-codoped fiber as an illustration. Robust, single-mode, single-polarization laser operation at temperatures in excess of 600°C is further achieved without compromising performance. A nonlinear, thermally induced wavelength shift is also observed at elevated temperatures.
