Connet 1.5um band single frequency pulsed fiber laser is a laser that generates optical pulses through an external modulator. The seed laser generally uses a narrow linewidth and low noise single frequency fiber laser such as CoSF-D or CoSF-R, or a single frequency semiconductor laser. Such a pulsed single-frequency fiber laser can maintain the spectrum and spectral characteristics of the seed laser, and the optical pulse quality is excellent, which is suitable for applications with high pulse requirements, such as a single-frequency narrow linewidth pulsed fiber laser.

Nanosecond (ns) short-pulse laser light sources generate optical pulses in the order of 100ps to 100ns through external modulators such as lithium niobate electro-optic modulators (LINbO3), which are usually used for shorter nanosecond (ns) pulses, such as <10ns.

Nanosecond (ns) long-pulse laser light sources generate optical pulses of the order of hundreds of nanoseconds to microseconds through external modulators such as acousto-optic modulators (AOM), and are usually used for longer nanosecond (ns) pulses, such as hundreds of nanoseconds.

Connet has very strong technical strength in the field of nanosecond (ns) pulsed fiber lasers. It produces pulse generation, shaping, high power amplification, nonlinear effects such as stimulated Brillouin scattering (SBS) suppression, stimulated Raman scattering SRS) suppression, self-phase modulation (SPM) and cross-phase modulation (XPM) suppression, four-wave mixing (FWM) suppression and other key technologies have a deep understanding. The working wavelength of the product can cover the 0.5um, 1.0um, 1.5um, 2.0um band.
