Experimental and theoretical study of longitudinal power distribution in a random DFB fiber laser.

We have measured the longitudinal power distribution inside a random distributed feedback Raman fiber laser. The observed distribution has a sharp maximum whose position depends on pump power. The spatial distribution profiles are different for the first and the second Stokes waves.

High efficiency supercontinuum generation using ultra-long Raman fiber cavities.

Supercontinuum generation in a multi-fiber ultra-long Raman fiber laser cavity is experimentally investigated for the first time. We demonstrate significantly enhanced spectral flatness and supercontinuum generation efficiency using only conventional single mode silica fiber. With a pump power of only 1.

Efficient 2.96 microm dysprosium-doped fluoride fibre laser pumped with a Nd:YAG laser operating at 1.3 microm.

A quasi-continuous wave Dy(3+)-doped ZBLAN fibre laser pumped by a ~1.3 microm Nd:YAG laser and operating at 2.96 microm with an emission linewidth of ~14 nm (FWHM) has been demonstrated.
