Laser Pulse Parameter Measurement——Photoelectric Detector


Pulse width is an important parameter of the pulsed laser and the measurement result is an important factor affecting the single pulse energy. At present, photoelectric detectors are commonly used in industrial production and scientific research to test the pulse width, convert optical signals into electrical signals, and read the waveforms and related parameters through an oscilloscope.
CNI can offers photoelectric detectors for monitoring ultra-fast pulsed laser and measuring their pulse width, rise time, repetition frequency, period and other parameters. For detecting high speed signals, a 50Ω load resistor is also recommended.
