The high-power nanosecond pulse fiber laser uses a high-power gain fiber module and cooperates with a dedicated drive and temperature control circuit to output high-peak and high-energy laser pulses. The laser wavelength and power are stable, RS232 serial port remote control, modular design facilitates system integration, and can be used for laser radar, distributed optical fiber sensing systems, etc.

Nanosecond fiber laser is a laser device with extremely high time resolution. The nanosecond-level pulse width enables the laser beam to reach extremely high peak power in a very short time, thereby achieving precise and rapid processing of the target. At the same time, by adjusting the repetition frequency, continuous or intermittent laser output can be achieved to meet the needs of different applications.
