A continuous wave Raman laser, with only 100 m of holey fiber as the Raman gain medium, is reported in a linear cavity all-fiber configuration. Slope efficiencies of 29% with a threshold of 2.7 W and 77% with a threshold of 3.7 W were achieved with a maximum output power of 3.6 W at 1.12 μm. The estimated holey fiber Raman gain coefficient of ∼17 W-1 km-1 is over 40 times larger than that of a standard telecommunication fiber.

    The scheme of a bidirectional ring fiber laser with a 90° Faraday rotator in the cavity has been theoretically studied. The Faraday rotator is employed as a nonreciprocal phase element producing splitting of natural frequencies of the laser cavity modes propagating in opposite directions. The...

    Based on refractive index W-profile, two kinds of single-mode fibers are proposed: polarizing (bend type) and linear polarization maintaining (PM-fiber) with low losses (up to 0.35 dB/km). The polarizing W-fiber allows one to combine the dichroism in wide spectral range with opportunity to have...
