Abstract
Few-cycle pulses are highly attractive for various applications in science and technology [1]. Among other applications one is closely linked to the generation of attosecond pulses which allows us to study various processes in atoms and molecules on the timescale of electronic motion [2]. The few-cycle pulses in the near-IR spectral band are now retrieved from well-known Ti:sapphire or Cr:forsterite solid-state laser systems due to their broad gain bandwidths [3]. Nonetheless, a development of competing fiber-based systems delivering few-cycle pulses is undoubtedly of great interest. In this work we proposed and realized all-fiber MOPA source emitting 29 fs (five-cycle) pulses with up to 2.6 nJ energy (100 mW average power) in the wide spectral band near 1.5 µm wavelength by means of the appropriate second order dispersion (GVD) and nonlinearity management of amplifying and compressing fibers.
