Abstract
In multicolor Coherent anti-Stokes Raman Scattering, a fingerprint region is a region densely filled with signals, and information about an intensity or spatial distribution of the signals is important for cell analysis. However, when laser power was increased due to the low signal intensity, there was a problem that cells were damaged. Thus, the present invention was configured such that the number of pulses of laser light emitted from a short pulse laser light source was changed by a pulse modulator. Accordingly, damage to the cells can be suppressed without significant reduction in signal intensity.
