Abstract
A laser light source includes a light source section for outputting pulse laser light λ1, λ2 with a mutually identical repetition frequency, an optical amplification section for amplifying and outputting the pulse laser light λ1, λ2 output from the above light source section by means of a common optical amplification medium, an optical demultiplexing section for mutually demultiplexing pulse laser light λ1, λ2, an optical multiplexing section for multiplexing and outputting the pulse laser light λ1, λ2 demultiplexed in the above optical demultiplexing section, and an optical path length difference setting section for adjusting an optical path length difference between the pulse laser light λ1, λ2 in between the optical demultiplexing section and the optical multiplexing section.
