Coherent laser beam
WebAug 2, 2013 · About this book. Laser beam combining techniques allow increasing the power of lasers far beyond what it is possible to obtain from a single conventional laser.One step further, coherent beam combining (CBC) also helps to maintain the very unique properties of the laser emission with respect to its spectral and spatial properties. WebApr 13, 2024 · A coherent laser beam was emitted from a pumped solid-state laser (λ = 532 nm) and extended using a beam expander. After passing through lens L1 (f = 100 mm), the expanded beam was focused onto a rotating ground-glass disk. Based on the van Cittert–Zernike theorem, a partially coherent beam was generated after the collimated …

WebIncoherent beam combination can be applied to end pumping a solid-state laser, where the pump light is injected along the direction of the beam rather than a transverse direction. Laser crystals made of materials such as Nd:YAG that can absorb pump radiation in both polarization directions can utilize this technique. WebLaser-based beam- through the hologram to be propagated in full to the imaging steering relies on coherent diffraction with a digital hologram plane [12-14]. With partially coherent illumination, this can be to send the light to the desired positions [8]. a …
