The QLD0593 series consists of compact visible light lasers with wavelengths of 532nm, 561nm, and 594nm, that consist of a DFB laser followed by a wavelength doubler. The DFB laser ensures a highly stable, high-speed modulation, and realize low power consumption of the module. The QLD0593 series lasers come in a small package and can have either a free space output or a fiber pigtail design.
