Connet 1064nm externally modulated nanosecond (ns) short pulse laser source produces the optical pulses from 100ps to 100ns level through an external modulator such as a Lithium Niobate Electro-Optic Modulator (LINbO3). This laser source is generally used for shorter nanosecond (ns) pulse, such as <10ns. The seed laser can be a semiconductor laser or a fiber laser. The way to generate the pulse via the external modulator can maintain the optical spectrum and the frequency spectrum characteristics of the seed laser and the optical pulse quality is excellent. This laser is suitable for the occasion with high demands for pulse, e.g. single frequency narrow linewidth pulsed fiber laser.

 

Connet has strong technical strength in the field of nanosecond (ns) pulsed fiber lasers and has a deep understanding on the key technologies of pulse generation, shaping, high power amplification and the nonlinear effect suppression such as stimulated Brillouin scattering (SBS), stimulated Raman scattering (SRS) and four-wave mixing (FWM). The operating wavelengths can cover 0.5um, 1.0um, 1.5um and 2.0um.
