Seeder for use with a fiber laser for generating an arbitrary shaped pulse, comprising an amplified spontaneous emission (ASE) source, a spectral filter and an arbitrary waveform generator (AWG) modulator, the ASE source for generating a continuous wave (CW) broadband pulse, the spectral filter being coupled with the ASE source for narrowing the CW broadband pulse, and the AWG modulator being coupled with the spectral filter for shaping the narrowed CW broadband pulse to an arbitrary pulse shape.

Arbitrary pulse shaping in high peak power fiber lasers

Narrow line width, high power pulses of optical radiation may be generated by the combination of stimulated emission and stimulated Raman scattering within a rare earth doped optical fibre (). The signals of a first () and second () seed laser sources are coupled into the fiber. The radiation of the pulsed first seed laser source () is amplified by stimulated emission of the rare earth ions so that the threshold for stimulated Raman scattering into the mode of the second seed laser sourceis exceeded, and efficient SRS transfers nearly all the power into the mode seeded by the second seed laser source ().

Generation of narrow line width high power optical pulses

Mode expander isolator for a fiber laser amplifier comprising an optical fiber input, an optical fiber output, an isolator and at least one lens, the optical fiber input for coupling a first optical fiber with the mode expander isolator, the optical fiber output for coupling a second optical fiber with the mode expander isolator, the isolator being positioned between the optical fiber input and the optical fiber output for preventing back-reflected laser light from reaching the optical fiber input and wherein the isolator and the at least one lens form a free space mode expander.
