Abstract: The output coupler free external cavity spectral beam combining structure uses the beam along 0-order and 1-order diffraction direction as the feedback light beam to realize the wavelength ...
These two paper sheets show drawings of parabolas. One is labeled: 1259 (/) Fig 2. It represents the equation x 2 + 4x + 4 = y. The other is labeled: Sheet 1266 (/) Fig 4. It represnts the equation x ...
Abstract: Smith-Purcell radiation (SPR), which occurs when electrons traverse a diffraction grating, is a promising candidate for tunable terahertz sources. Recent advancements in enhancing ...
