Laser microscope apparatus having a frequency dispersion adjuster

摘要

To enable both observations of coherent anti-Stokes Raman scattering light and multiphoton fluorescence in a same apparatus so as to observe a specimen by various observation methods. There is provided a laser microscope apparatus comprising: two optical paths for guiding pulsed laser beams having two different frequencies whose frequency difference is approximately equal to a specific molecular vibration frequency in a specimen; a multiplexer for combining the pulsed laser beams guided through these two optical paths; and a frequency dispersion adjuster which is provided on at least one of these two optical paths, and is capable of adjustment to approximately equalize frequency dispersion quantities of the pulsed laser beams guided through the two optical paths.
