abstract

High power (HP) laser diodes with apertures around 100um pump solid state and fiber lasers, used for material processing. The necessity for the second stage lasers originates from the well-known limitation of brightness of laser diodes with the aperture increase due to appearance of multiple lateral modes. For the first time we report suppression of lateral modes of 100um wide laser diodes by digital planar holograms. Digital planar hologram narrows spectrum of laser diodes, similar to simple gratings, used in DFB and DBR lasers.
