ABSTRACT:
A scanning laser microscope that can quantitatively display a laser irradiation power on a display unit and that can suppress fluctuations in the laser irradiation power is provided. The scanning laser microscope includes a light source configured to emit laser light, a scanning unit configured to scan the laser light emitted from the light source on a sample, a photodetector configured to detect light from the sample, a processing unit configured to convert a signal from the photodetector into an image signal of the sample and to output the image signal, a reference light detector configured to detect part of the laser light emitted from the light source as a reference light signal, a laser light control unit configured to control the power of the laser light emitted from the light source, an irradiation-power calculation unit configured to calculate an irradiation power value at the sample on the basis of the reference light signal detected by the reference light detector, and a display unit configured to display the calculated irradiation power value at the sample.
