Potential application of a green fiber laser in laser display systems

This study explores the application of optical fiber lasers in display systems by integrating a Pr3+-doped green all -fiber laser into a laser projection display system. As a control group to compare the results, a 520 nm semiconduc-tor green laser diode module was integrated, similar to the experimental group. The color gamut and speckle per-formances were studied and compared. The results showed that the experimental group performed slightly better in the color gamut volume. The speckle contrast decreased rapidly in the experimental group when power increased. To our knowledge, this is the first study to apply a fiber laser to a laser display system. The results shed light on devel-oping laser display systems with fewer or no speckle reduction elements. (c) 2023 Optica Publishing Group

Automated summary

This study investigates the use of optical fiber lasers in display systems by integrating a Pr3+-doped green all-fiber laser into a laser projection display system. A 520 nm semiconductor green laser diode module was integrated as a control group for comparison. The color gamut and speckle performances were studied and compared. The experimental group showed slightly better performance in color gamut volume, and the speckle contrast rapidly decreased with increasing power. This study is the first to apply a fiber laser to a laser display system, providing insights for developing speckle-free or speckle-reduced laser display systems.
