A novel method for the control of stimulated Raman scattering and hot electron production in short-pulse laser-plasma interactions is proposed. It relies on the use of a linear frequency chirp in nonbandwidth limited pulses. Theoretical calculations show that a 12% bandwidth will eliminate Raman forward scattering for a plasma density that is 1% of the critical density. The predicted changes to...

Amplification of ultrashort solitons in fiber amplifiers is discussed by considering a general model that includes gain saturation, gain dispersion, and intrapulse stimulated Raman scattering. The numerical results show that an interplay between gain dispersion and intrapulse Raman scattering can lead to novel temporal and spectral features. Under high-gain conditions the input pulse is found t...

The conventional spontaneous Raman microscopy is a powerful tool that images chemical bonds in materials, but it suffers from the intrinsically weak cross-sections and requires long acquisition time. As an emerging imaging tool, stimulated scattering (SRS) significantly amplifies signal. It has higher sensitivity, faster speed, fine spatial resolution. Meanwhile, label-free capable of 3D imagin...
