Laser Pulse Parameter Measurement (High-speed Photodetector)

Laser pulse duration, usually refers to the interval between the time when the laser power maintains at a certain value. The pulse duration of different lasers can vary greatly.

High-speed photodetector combined with oscilloscope can monitor ultra-fast pulsed laser and measure pulse duration, frequency, period and other parameters of lasers.
