Abstract

A tunable laser is disclosed in which a plurality of laser beams different from one another in wavelength and polarization can be simultaneously oscillated. The tunable laser is advantageous among others in that an atomic absorption spectroscopic analysis can be carried out with very high sensitivity when it is used as, for example, a light source for two-wavelength measurement in the atomic absorption spectroscopic analysis.
