Abstract
We present our recent developments in utilizing a compact and portable light source for high-speed multicolor stimulated Raman scattering imaging (SRS) in biomedical and medical environments. The source combines a rapid and wide tunability for accessing Raman bands between 700 and 3300 cm-1 with high stability in terms of power (deviation < 0.3 %) and wavelength (deviation < 0.5 pm) over more than 100 h. We were able to shorten the Stokes pulse duration to below 3ps, resulting in a twofold increase in SRS signal intensity compared to our previous version (7ps).
