Generation of Wavelength-Tunable Picosecond Pulses with Polarization-Maintaining Yb Figure-Nine Laser for Stimulated Raman Scattering Microscopy

We present an environmentally stable, high-speed wavelength-tunable laser system with a tunability of >280 cm−1. This laser is synchronized to a picosecond Ti:sapphire laser to demonstrate video-rate hyperspectral stimulated Raman imaging of polymer beads.
