How ALPD laser technology suppresses speckle

In the face of the speckle problem, Appotronics' ALPD laser technology adopts a strategy to eliminate speckle from the source. They cleverly introduced nano-luminescent rare earth materials to emit a large amount of incoherent light while mixing a very small part of the laser to form speckle-free white light, thereby eliminating the coherence of the laser from the source. This technical solution does not require any additional measures, has no negative impact on the system, and has good compatibility, low cost, and high reliability.
