A laser beam shape is typically defined by its irradiance distribution and phase. The latter is essential in determining the uniformity of a beam profile over its propagation distance. Therefore, beam shapers are designed to redistribute the irradiance and phase of an optical beam to attain a desired beam profile that is … Visa mer In low-performance systems where cost is a driving factor, Gaussian beams may be physically truncated by an aperture to form a pseudo-flat top profile. This is inefficient and wastes the energy … Visa mer Diffractive beam shapers utilize diffraction, rather than refraction, to shape the laser beam into a specific irradiance distribution. Diffractive … Visa mer So far, we have discussed shaping light using field mapping or beam integration where diffraction effects play major roles in the design and … Visa mer A laser beam integrator, or homogenizer, is composed of multiple Ienslets that divide the beam into an array of smaller beams, or beamlets, followed by a lens or other focusing element that superimposes the beamlets at the … Visa mer WebbLASERTEC 75 Shape World Map New improved machine concept Fibre laser with 100 W (1.000 kHz) and new, compact laser head design Fast Scan Mode for similar texturing quality also at high scanning speeds …

Webb2 nov. 2024 · In laser-based powder bed fusion of metals (PBF-LB/M), the laser beam shape significantly influences the temperature distribution and melt pool dimensions. … WebbPulsed lasers are lasers which emit light not in a continuous mode, but rather in the form of optical pulses (light flashes). The term is most commonly used for Q-switched lasers, which typically emit nanosecond pulses, but this article gives an overview of a wider range of pulse-generating lasers. imperial war museum london england
