Shaping up a Laser (image) Princeton University, Engineering School Share Print E-Mail Caption Engineers at Princeton found that by carefully shaping the area to which energy is delivered within a laser can dramatically improve the laser's performance. The researchers developed a mathematical approach to optimizing the pattern of energy delivery to achieve a desired outcome. In the case shown, pumping energy into a diamond shape produces powerful directional emission of light from the laser.
