Buying Sum and Difference Frequency Generators

Top-level product category: nonlinear optics

More general product categories: nonlinear frequency conversion equipment

Related product category: mid-infrared laser sources

Nonlinear frequency conversion techniques, such as sum and difference frequency generation, enable the creation of new wavelength components across the infrared, visible, and ultraviolet ranges. These methods are also used to generate terahertz radiation, expanding the versatility of laser sources.
