Optical fibres with depressed claddings for suppression of coupling into cladding modes in fibre Bragg gratings

Autor: Dong, L., Reekie, L., Cruz, J.L., Caplen, J.E., de Sandro, J.P., Payne, D.N.

A new method for suppression of coupling from guided optical modes into cladding modes in an optical fiber Bragg grating using a fiber with a strongly depressed cladding is proposed. Strong suppression of the coupling has been demonstrated both theor

158µJ pulses from a single transverse mode, large mode-area EDFA

Autor: Taverner, D., Richardson, D.J., Dong, L., Caplen, J.E., Williams, K., Penty, R.V.

We report the amplification of 10pJ-100pJ, semiconductor diode pulses up to an energy of 158µJ and peak powers >100kW in a multi-stage fibre amplifier chain based on a single-mode, large mode-area erbium doped amplifier design. These results represe

Frequency-doubling of a cladding-pumped Er3+/Yb3+ femtosecond fiber laser system using a periodically-poled LiNbO3

Autor: Fermann, M.E., Galvanauskas, A., Harter, D., Minelly, J.D., Caplen, J.E., Arbore, M.A., Fejer, M.M.

As real-world ultra-fast optical devices proliferate, there is a growing need for highly reliable and compact sources of femtosecond pulses [1]. Currently most of these applications require moderate power sources operating around 800 nm, which is ide

Cladding-pumped fibre laser/amplifier system generating 100µJ energy picosecond pulses

Autor: Minelly, J.D., Galvanauskas, A., Harter, D., Caplen, J.E., Dong, L.

We report on a fibre amplifier system generating picosecond pulses with 100µJ energy. A mode-locked fibre oscillator is used to seed a multi-stage acousto-optically gated fibre amplifier. The final stage comprises a cladding pumped multimode Er3+/Yb

Cladding mode coupling suppression in fibre Bragg gratings using fibres with a depressed cladding

Autor: Dong, L., Reekie, L., Cruz, J.L., Caplen, J.E., Payne, D.N.

We have demonstrated both theoretically and experimentally strong suppression of coupling of the guided fundamental mode into cladding modes in a Bragg grating by introducing a depressed cladding around the core region. We have also studied the effec

Broad-area diode-pumped 1W femtosecond fiber system

Autor: Galvanauskas, A., Fermann, M.E., Harter, D., Minelly, J.D., Vienne, G.G., Caplen, J.E.

Summary form only given. High-average-power 310-fs pulses were obtained with an all-fiber chirped pulse amplification (CPA) system. Both the oscillator and the power amplifier are based on Er/Yb-doped fiber for cladding-pumping with broad-area laser

Cladding pumped erbium fibre amplifier generating femtosecond pulses with an average power of 0.26W

Autor: Fermann, M.E., Galvanauskas, A., Harter, D., Minelly, J.D., Caplen, J.E., Chen, Z.J., Payne, D.N.

Femtosecond pulse amplification in a cladding pumped fiber amplifier is demonstrated for the first time. A cladding-pumped Er3+ doped fiber amplifier generates 380fsec near-bandwidth-limited pulses at repetition rates up to 50MHz with an average powe

Long-pulse coherent waveforms from a fiber laser

Autor: Minden, M., Bruesselbach, H., Gaeta, C., Kost, A., Hasenberg, T., Rockwell, D., Allen, R., Keller, U., Chiu, T.H., Minelly, J.D., Caplen, J.E., Reekie, L., Ball, G.

Passively modelocked long-pulse lasers were made using fiber gratings, MQW nonlinear reflectors and active fiber media. Singlemode Nd- and Er-doped fibers and cladding-pumped fiber lasers operated in high-stability and multi-pulsing regimes.
