Abstract

The possibility to scale-up output pulse energy in diffraction-limited Er-doped fiber amplifier has been studied. It is shown that the utilization of tapered fiber design allows one to increase the pulse energy up to 2 mJ, while keeping the diffraction-limited beam quality (M2~1.4). Factors limiting the further increase in pulse energy are revealed.

Author

Maksim M. Khudyakov, Andrei E. Levchenko, Vladimir V. Velmiskin, Konstantin K. Bobkov, Svetlana S. Aleshkina, Mikhail M. Bubnov, Mikhail V. Yashkov, Aleksei N. Gur’yanov, Leonid V. Kotov, and Mikhail E. Likhachev

Subjects
taper, Er-doped, high efficiency, high peak power, self-phase modulation, very large mode area, Applied optics. Photonics, TA1501-1820
Abstract

A tapered Er-doped fiber amplifier for high peak power pulses amplification has been developed and tested. The core diameter changed from 15.8 µm (mode field diameter (MFD) 14.5 µm) to 93 µm (MFD 40 µm) along 3.7 m maintaining single-mode performance at 1555 nm (according to the S2-method, the part of the power of high-order modes does not exceed 1.5%). The amplification of 0.9 ns pulses with spectral width below 0.04 nm up to a peak power above 200 kW (limited by self-phase modulation) with a slope pump-to-signal conversion efficiency of 15.6% was demonstrated.
