A laser microscope (1, 1') includes a laser light emitting system (3, 48) which emits a pump beam ( omega 1) and a Stokes beam ( omega 2) having different frequencies, and a common optical fiber (20) having one end (20a) and the other end (20b). The pump beam ( omega 1) and the Stokes beam ( omega 2) emitted from the laser light emitting system (3, 48) are incident on the one end (20a) thereof and emitted from the other end (20b) thereof. A beam irradiating mechanism (33) condenses and irradiates the pump beam ( omega 1) and the Stokes beam ( omega 2) emitted from the other end (20b) of the optical fiber (20), onto a sample (34) via the objective lens (32), thereby making an anti-Stokes beam ( omega 3) be emitted from the sample (34). A photo detector (40) detects the anti-Stokes beam ( omega 3) emitted from the sample (34). A beam selecting mechanism (38) allows only the anti-Stokes beam ( omega 3) of the pump beam ( omega 1), the Stokes beam ( omega 2) and anti-Stokes beam ( omega 3) to be received on the photo detector (40). <IMAGE> |
