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.
