Paper Abstract

We experimentally demonstrate a compact self-aligned external cavity 25W high power laser diode bar at 976 nm tunable over 0.5 nm with a bandwidth of 0.25 nm. The external cavity is based on double diffraction from a glass reflective volume holographic grating (VHG). The wavelength tuning is performed by rotation of the VHG. Passive alignment and fine wavelength tuning of the proposed external cavity are attractive new features over the state-of-the-art active alignment method and fixed wavelength limitation currently used in wavelength stabilized high power laser diode bars.
