摘要: The invention relates to a method and device for determining the output power of semiconductor laser diode, which is operated with diode current (Id). According invention, defined measuring (Im), less than threshold (HLD) conducted in conducting direction through (HLD). forward voltage (Uf) decreasing over measured, temperature laser-active region determined from measured by using at least one calibration curve. makes simple precise determination possible without requiring an additional device, example, monitor diode.
