METHODS AND APPARATUS FOR GENERATING TERAHERTZ RADIATION

摘要

Methods and apparatus for generating terahertz radiation are disclosed herein. In addition, methods for forming orientation-patterned nonlinear semiconductor crystals are disclosed herein. For example, according to an example implementation, a method for generating terahertz radiation may include: providing an optical pulse having a wavelength less than approximately 1.0 μm; and illuminating an orientation-patterned nonlinear semiconductor crystal with the optical pulse.
