How Pulsed Laser Welding Works and Applications
How a pulsed laser performs depends on pulse energy, pulse length, pulse height, and repetition rate. The pulse energy is the energy per pulse of the laser, and the pulse length is the length of time of a pulse. The height of a laser pulse is the laser''s peak power measured in kW, while the repetition rate is the number of pulses per second.
