摘要
We present a novel device for automatically aligning laser beams using two quadrature photodiodes set immediately behind slightly transparent Mirrors. The system utilizes feedback electronics and a LABVIEW program to automatically align an ultrafast laser quickly and accurately, even in the presence of gross thermal warping of the optical table. The design and implementation of this device is straiahtforward, making it an ideal research project for undergraduate students. (C) 2004 American Association of Physics Teachers.
