ABSTRACT:
A laser microscope includes a laser light emitting system which emits a pump beam and a Stokes beam having different frequencies, and a common optical fiber having one end and the other end. The pump beam and the Stokes beam emitted from the laser light emitting system are incident on the one end thereof and emitted from the other end thereof. A beam irradiating mechanism condenses and irradiates the pump beam and the Stokes beam emitted from the other end of the optical fiber, onto a sample via the objective lens, thereby making an anti-Stokes beam be emitted from the sample. A photo detector detects the anti-Stokes beam emitted from the sample. A beam selecting mechanism allows only the anti-Stokes beam of the pump beam, the Stokes beam and the anti-Stokes beam to be received on the photo detector.
