ABSTRACT:
This laser scanning microscope has a second light source for emitting second light into one of branch channel waveguides, and a third photodetector for detecting a light intensity distribution formed on the end face of the trunk channel waveguide based on the second light, and a controller for controlling the voltage to be applied from a voltage application unit to electrode on the waveguide in accordance with the output signal from the third photodetector.
