Description

technical field [0001] The invention relates to laser frequency locking technology, in particular to a frequency locking device for a dual-wavelength external cavity resonance system. Background technique [0002] Dual-wavelength external cavity resonance is one of the important technologies to realize nonlinear optical frequency conversion. Generally speaking, nonlinear optical frequency conversion is to achieve frequency conversion of two wavelengths of light by focusing two laser beams and overlapping them in a crystal. However, the conversion efficiency of a crystal is usually proportional to the square of the optical power density, so two lasers are directly converted. Very inefficient. Dual-wavelength external cavity resonance, as a technology that can improve the efficiency of nonlinear optical frequency conversion, has been widely used in related fields, mainly by selecting appropriate cavity structure parameters such as cavity length, cavity mirror curvature radius...
