850nm nanosecond pulse laser light source
Product description
ROF -PLS series 850nm nanosecond pulsed light source(laser modulator) uses a unique short pulse drive circuit to achieve the narrowest up to 3ns pulse output. In contrast, the use of high stability of the laser and the unique APC (automatic power control) and ATC (automatic temperature control ) Circuit, so that the output power and wavelength has a high degree of stability, and real-time monitoring of light source temperature, energy, and other information. The series of pulsed light sources are mainly used in MOPA structure fiber laser seed source、 spectral analysis、optical fiber sensing, passive device testing.
