You can easily reduce the repetition frequency of the pulse laser you have.
Manufacturer: PriTel (USA) PriTel's compact pulse picker "OPP-AO" series is a device that can extract single pulses from a pulse train. It has a built-in AO modulator and is used by connecting it to a laser and optical patch cord to set the picking ratio. It is also capable of synchronization with external signals. The countdown prescaler in the driver circuit selects the output pulses, and the preset delay function controls the phase of the electrical and optical pulses. It boasts low insertion loss and a high extinction ratio of >40dB. It is widely used in applications such as research and development, optical switches, optical frequency combs, and fiber laser development.
