Abstract

By synchronously pumping a loop of fiber with ≈10-ps pulses from a mode-locked color center laser, we demonstrated the first Fiber Raman Amplification Soliton Laser (FRASL). The FRASL output pulses are determined by pulse compression and soliton pulse shaping in the fiber and have to date been as short as 240 fs. The lasing wavelength can be time dispersion tuned.¹ The single-cavity FRASL is a much simpler configuration than the color center soliton laser,² which consists of two coupled cavities and requires feedback stabilization to overcome interferometric instabilities.
