Wavelength-tunable high-energy soliton pulse generation from a large-mode-area fiber pumped by a time-lens source.

We demonstrate high-energy soliton generation from 1560 nm to 1700 nm using soliton self-frequency shift in a large-mode-area fiber. A 1.5 ps time-lens source at 1544 nm is used as the input source. The combination of a time-lens source and soliton self-frequency shift in a large-mode-area fiber enables a turn-key, high pulse quality, wavelength-tunable, energetic femtosecond source with arbitrary pulse repetition rate.
