DLightS provides continuous energy output up to 1,800W/mm2, achieving ＞95% beam uniformity and ＞98% output power stability.
This system combines eutectic bonding technology, thermal management and thermal stress control technology for photon generation, beam transformation and beam homogenisation technology for photon control
The large line shaper offers line angles greater than 150mRad, while maintaining diffraction limited line width
The system's on-the-fly spot and variable laser energy provide selective heating of the pinning layer in each sensor to 'imprint' the intended magnetic orientation
