Non-linear optical processes are effective label-free methods for molecular sensing and imaging. An essential consideration for implementing nonlinear optical spectroscopy and imaging is the ultrafast laser source. Applications, such as coherent Raman spectroscopy and imaging, also require wavelength tunability and multiline outputs. Existing solid state systems are complex, costly and bulky. Fiber-based systems, on the other hand, are cost-effective and easier to use. Here we present the development of a divided pulse soliton self-frequency shift source capable of generating multi-line, ultrashort pulses with broadband tunability, while keeping a compact footprint. Recent experimental progress will be discussed.
