Abstract

We present recent developments on our portable light source for multicolor coherent Raman imaging. The source combines a rapid and wide tunability for accessing Raman bands between 700 and 3200 cm-1 with high stability for long term measurements utilizing software PID-stabilization by means of an integrated optical miniature spectrometer. We present a long-term power stability with a standard deviation of less than 0.3% and a wavelength stability of better than 5pm over the course of 100h. This development constitutes an important step for advancing CRI microscopy in terms of portability and stability for applications in medical diagnostics or environmental sensing.
