ABSTRACT:
A laser microscope is provided in which a beam splitter extracts a part of a laser light of two wavelengths λ1=488 nm and λ2=514.5 nm, a prism spectrally resolves the laser light of the two wavelengths λ1and λ2, a two-split photodiode detects intensities of two lines spectrally resolved in this manner, and a controller controls an acousto-optical tunable filter (AOTF) fixed to an output end of an argon laser based on a detection signal outputted from the two-split photodiode so that respective light intensities of both lines of wavelengths λ1and λ2become constant.
