Liteons low-cost algainp laser diode emits a highly visible 650 nm output light with low threshold current and high output efficiency. A diffraction-limited single spatial mode beam output allows for easy collimation with readily available optics. The active layer is a mock grown, strained Quantum well epitaxial structure. The high output efficiency is achieved by optimized device structure design. Both laser facets are coated with multilayer dielectric to assure high performance and reliability. Liteons LTLD505T is ideal for pointing, alignment, and bar Code Scanning applications.
