Original Abstract Submitted
A laser interferometer includes: an interference optical system including a laser source configured to emit laser beams and to cause the laser beams to interfere with each other; a gas cell configured to seal a gas absorbing light having a predetermined wavelength and allow the laser beams to be incident; an detector configured to detect an amount of light emitted from the gas cell and output an emitted light amount detection signal; and a light source controller configured to control a wavelength of the laser beams based on the emitted light amount detection signal.
