Author Affiliations +
We present the first spatiotemporally mode-locked fiber laser with self-similar pulse evolution, to the best of our knowledge. Our multimode fiber laser produces amplifier similaritons with near-Gaussian beam quality (M2<1.4) at the output. Ytterbium based laser generates 2.3 ps pulses at 1030 nm with 2.4 nJ energy. The output pulses are externally compressed to 192 fs with a grating compressor. Intracavity large spectral breathing (>6) and less chirped pulses than the cavity induced total dispersion are the verifications of the spatiotemporal self-similar pulse propagation.
