Abstract: A multi-mode microlaser and a method for driving a multi-mode broad­area microlaser such as a multi-mode VCSEL is described such that the multi­mode microlaser shows an unexpected Gaussian-like far-field intensity distribution. The driving conditions are in general determined such that a strong reduction of the degree of spatial coherence occurs. For square pulsed driving current, these conditions are determined by the pulse duration p d and the pulse height p h . A Gaussian-like far-field intensity distribution is obtained for pulsed multi-mode broad area microlasers. The typical spatial coherence area corresponding with these driving conditions is substantially independent of the Fresnel number of the rnicrolaser. Additionally, this partial spatial coherence can be tuned by changing the driving conditions, such as e.g. the pulse shape and length.

Abstract: The invention relates to a device and a method for exposing photosensitive plates (33) for printing presses, comprising controlled laser exposure apparatus and a conveyor system for moving forward the photosensitive plates. The problem with the plate exposers at present is that they are not sufficiently accurate. A device is therefore provided whereby the controlled laser exposure apparatus (63) comprises means (1, 20) for measuring and compensating the variances in the laser beam orientation. The controlled laser exposure apparatus (63) comprises a software control (21). Another problem is that one laser source cannot bridge the scanning of photosensitive plates (200) with great width. Two laser sources (2) synchronised with each other are therefore provided. The invention further relates to a housing for a device such as specified above.
