摘要：
We describe a beam-combining technique for three high-power laser-diode stacks to effectively increase the power density. Employing this beam-combining technique using two slit-stripe mirrors, the power density increased to 722 W/cm(2) from a raw power density of 291 W/cm(2) by combining the beams of three high-power laser-diode stacks. We also achieved a focused power density of 250 kW/cm(2) by focusing the combined beam of the three high-power laser-diode stacks with a lens of 40 mm focal length.
