Ultrafast fiber lasers have gained rapid advances in last decades for their intrinsic merits
such as potential of all-fiber format, excellent beam quality, superior power scalability, and …

Recent developments in nonlinear optics have led to the discovery of a new class of
ultrashort pulse, the 'optical similariton'. Optical similaritons arise when the interaction of …

Isotope shifts in the nuclear charge radius of even and odd calcium isotopes are calculated
within the nuclear shell model. The model space includes all configurations of nucleons in …

We numerically and experimentally demonstrate that pulses with a parabolic intensity profile
can be formed by passive reshaping of more conventional laser pulses using nonlinear …

Parabolic pulse generation around 1550 nm in dispersion decreasing comb-like profiled
fibre is experimentally demonstrated. A six-segment comb profile based on two types of …

The relationship between the self-similar propagation region for single pulse and oscillation
region for a pair of self-similar pulses are first investigated in our paper. By introducing self …

We investigate the interaction between optical parabolic pulses in a Raman fiber amplifier.
Self-similar amplification of two identical time-delayed pulses creates an oscillation which …

We consider the self-similar amplification of two optical pulses of different wavelengths in
order to investigate the effects of a collision between two similaritons. We theoretically …

Pulses compression has been widely studied for a long time. In order to generate excellent
self-similar pulses in a dispersion-decreasing optical fiber with normal group-velocity …

We design and demonstrate a high repetition-rate similariton generation system using
normal dispersion fiber amplifiers (NDFA's). We numerically calculate the pulse evolution in …
