Rof Nanosecond pulsed laser Modulator Laser Light Source ns Pulse Laser module

Short Description:

Rof-PLS series pulse light source (Nanosecond pulse laser)uses a unique short pulse drive circuit to achieve the narrowest pulse output up to 3ns, while using a highly stable laser and a unique APC(automatic power control) and ATC(automatic temperature control) circuit to make the output power and wavelength have high stability and can monitor the temperature, power and other information of the light source in real time. This series of pulse light source is mainly used for MOPA structure fiber laser seed source, spectral analysis, fiber sensing, passive device testing.
