Beam Combining for Three High-Power Laser-Diode Stacks with a Stripe Mirror Technique
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...

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. |
