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.

摘要： The invention provides a compact laser light source whose wavelength can be designed freely in a wavelength band in which the semiconductor laser has not been put to practical use by combining an efficient nonlinear optical crystal and high-power semiconductor lasers for optical communication. In one embodiment, the laser light source includes: a first laser for generating a laser beam of a wavelength λ1; a second laser for generating a laser beam of a wavelength λ2; and a nonlinear optical crystal that allows the laser beam of wavelength λ1 and the laser beam of wavelength λ2 as inputs and outputs a coherent beam having a wavelength λ3 of a sum frequency that satisfies a relationship of 1/λ1+1/λ2=1/λ3. The wavelength λ3 of the sum frequency is 589.3±2 nm that is equivalent to the sodium D line.
