Abstract
We developed two beam laser diode array as a light source of a laser printer which prints multi-line in a single scan. The device consists of a monolithic two beam laser diode array and a monitoring photo-diode. Each beam can be operated independently. The typical lasing wavelength is 785nm, and the light output power is 5mW at operation current of 50mA. Full angles at half maximum points of far-field patterns in parallel and perpendicular planes are 10° and 30° respectively. The difference of optical characteristics between the two laser beams in one chip are small, ex., the difference of lasing wavelength is typically 1.8nm.
