For many laser applications, such as marking, additive manufacturing, material treatment, scientific research, etc. short pulses with high diode currents are required. For these applications diode currents of 100A … >200A with rise times of 20–50ns are often needed. In addition, the pulsesshall have a clear rectangular shape with short rise time, steep rising edges, no overshoot and no ripple. This article shows the physical restrictions and explains technical solutions how laser diode drivers can realize high diode currents with very short pulse lengths.
