Abstract: PURPOSE:To obtain a simple optical frequency marker by mounting a Fabry- Perot resonator, to which output beams from a light source are projected, and generating an optical output having peaks at predetermined wavelength intervals from the Fabry-Perot resonator. CONSTITUTION:A light source 1 outputs beams having wide spectral band width as shown in the graph A, and the beams are changed into paral lel beams, and are projected to a Fabry-Perot resonator 3 and resonate between semitransparent mirrors 31, 32. When cavity length (the distance of the semitransparent mirrors 31, 32) is represented by L, light velocity by (c) and a refractive index by (n), the transmittance of the Fabry-Perot resonator has steep peaks at every c/2nL as shown in the graph B. When an electric field is applied to an electrooptic crystal 4 by a control signal source 5, the refractive index of the electrooptic crystal 4 changes, and equivalent cavity length varies. Consequently, the wavelength of output beams changes, an optical frequency reference marker at variable frequency intervals can be realized by simple constitution, and stable frequency intervals can be acquired when the Fabry-Perot resonator is introduced to a thermostat, etc. and a temperature is controlled.
