1064nm Externally Modulated Nanosecond Short Pulse Laser Source
Time:2020.04.09 Source: Author:
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.

【Remark】
1. The output power is measured with the optical connector.
2. The usage of this laser source is typically set to 5ns/50KHz with the output average power up to W level. If the repetition rate of < 50KHz needs to be used, please use the laser with the peak power to be less than 4KW.
3. Please pay attention to keep the end face clean when using the laser for the high output power.
