| 英文摘要 | 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 pd and the pulse height ph. 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. |
