The invention relates to an array
light source light splitting device and method. The device comprises a seed source for inputting
signal light,
fiber amplifiers connected with the seed source, and a light splitter connected with the
fiber amplifiers, wherein the light splitter is provided with N paths of fibers, the N is a natural number, and the
signal light of the seed source is split by the light splitter into N paths which are outputted. According to the device, the
signal light of the seed source is split by the light splitter into the N paths which are outputted, the N paths of
signal light are amplified through the
amplifier of each
branch for power amplification, and multiple paths of
signal light are outputted; repetition frequency of 1550 nanometer
laser can reach megahertz, so the
laser has a relatively high
water absorption coefficient, when the
laser in with the
wave band radiates to eyes, an eye damage threshold is relatively high, but the
wave band laser of the device has
eye safety characteristics; a synchronization work mode can be employed in a
light source, and the device has wide application prospects in the automatic driving and 3D scanning field.
