Biased Photodetector for measuring parameters such as pulse width, rise time, repetition frequency and period.

Laser Pulse Parameter Measurement--Biased Photodetector

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, biased 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 free-space bias photodetectors 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.

As the leading manufacturer and supplier in China, CNI is dedicated to offer best quality lasers , laser systems, High Power Laser, optical measuring equipment, Single Longitudinal Mode Laser, laser processing equipment, High Energy Laser,machine vision and the photoelectric detection equipment.
