2. Mechanism of the Direct Diode Laser
The direct diode laser consists of a power supply, light source, optical ber, output
unit, etc. Laser light can be transferred to a place remote from the main unit by
optical fiber, so that only the optical fiber and output unit can be mounted in the
manufacturing line for processing. Multiple beams of laser light can be split from
single laser equipment to multiple optical bers.
Powersharing
When single laser light is split into multiple beams by using a beamsplitter, multiple
workpieces (or multiple positions of a single workpiece) can be simultaneously
welded. This method is called "powersharing."
Supposing that the energy of a single laser light beam is 100% or 50% laser light is
simultaneously irradiated when the number of deliveries is 2. Up to 2 deliveries are
available for this laser equipment at powersharing.
