Wavefront reconstruction of high power laser diode array

Silica-taper array for beam shaping of high power laser diode bar

“…This complicated intensity distribution of LDB makes it necessary in nearly all applications that the beam shaping process need to be done first. 3) Several approaches have been proposed to beam shaping and concentration of the high power LDB: micro-optics array devices (micro-lens or micro-prism), 4,5) diffractive optical elements devices, 6,7) subbeams-rearrange devices, 8,9) and non-imaging devices. [10][11][12] However, as attractive means for the laser beam shaping of LDB, they are expensive, together with inconvenience in the design and manufacture of the optical elements, have raised the costs of the whole semiconductor laser sources.…”
