摘要： A light source apparatus with modulation function has a wavelength conversion module (75) composed of a nonlinear optical material with a structure having a nonlinear constant modulated periodically. It outputs a difference frequency or sum frequency produced by multiplexing pumping light from semiconductor laser light sources (71) and (72) with different wavelengths through a WDM coupler (74) and by launching the multiplexed light into the optical waveguide. The semiconductor laser light source (72) includes a diffraction grating. The semiconductor laser light source (71) includes a section for modulating output light emitted from its semiconductor laser, and is connected to an external FBG (73) which has a reflection band narrower than a resonance wavelength spacing determined by the device length of the semiconductor laser. The FBG (73) is supplied with the modulated output.

摘要： A laser light source is disclosed consisting of first and second lasers that respectively generate laser beams of wavelengths λ1 and λ2. Wavelength λ1 is in the range of 0.9-1.0 μm. A nonlinear optical crystal uses the laser beams of wavelengths λ1 and λ2 as inputs, and outputs a coherent beam having a wavelength λ3 of a difference frequency that satisfies a relationship of 1/λ1−1/λ2=1/λ3. The nonlinear optical crystal has a periodically poled structure of a single period. The wavelength λ3 of the difference frequency varies between 3.1 μm and 2.0 μm when the wavelength λ2 varies between 1.3 μm and 1.8 μm.
